Comment: + “Appearance” panel for Ubuntu desktop
Deletions are marked like this. Additions are marked like this.
Line 1: Line 1:
== Phone == <<TableOfContents>>
Line 3: Line 3:
On the phone, apart from [[Accessibility/Specs/Settings|accessibility settings described elsewhere]], the only visual configuration should be setting the background pictures for the welcome screen and home screen. == Ubuntu desktop ==
Line 5: Line 5:
{{attachment:phone-background.png}} A single “Appearance” panel should provide a setting for choosing a Yaru variant (Light, Standard, or Dark), and settings for the Launcher.
Line 7: Line 7:
In the “Background” panel, “Welcome screen” and “Home screen” should be thumbnails of the actual screens — complete with tint and infographic for the welcome screen, and Dash contents for the home screen. This is to convey whether, and if so how much, the current background makes each screen less readable. {{attachment:appearance-settings-2020.png}}
Line 9: Line 9:
Whenever “Same background for both” is set, the welcome screen and home screen previews should function as a single tappable button, navigating to a “Choose Background” screen. Whenever “Different backgrounds for each” is set, the previews should function as two separate buttons, navigating to a “Welcome Screen” or “Home Screen” screen respectively. If you have any other themes installed (excluding the High Contrast theme), they should appear following the Yaru variations in the list, in alphabetical order, each with a generic theme icon (since theme packages do not provide any preview image). If any theme has an installed dark variant, it should appear as a separate item in the list (since that’s how the Yaru variants are presented).
Line 11: Line 11:
{{attachment:phone-background-chooser.png}} Choosing any of the theme options should set the toolkit and cursor theme simultaneously. In the case where different themes have been set for toolkit and cursors (for example, using gnome-tweak-tool), a temporary option “Custom” should be present and selected as the last item in the list.
Line 13: Line 13:
All three of those chooser screens should consist solely of a list, with items for “Ubuntu Art”, “Camera Photos” (insensitive if there are none), and an item for each album in the gallery, each sensitive if it contains photos (or one insensitive “Gallery is empty” item if there are no albums). '''Test case:''' In the Gallery, create an album with no photos. Switch to this screen in System Settings: the album should be represented by an insensitive item. Switch back to the Gallery and put a photo in the album. Switch back to this screen in System Settings: the album’s item should now be sensitive. Whenever the “Appearance” panel opens, the list of themes should be scrolled, if necessary, to show the current selection.
Line 15: Line 15:
{{attachment:phone-background-chooser-album.png}} == Theme snap installation ==
Line 17: Line 17:
Choosing any of the items should navigate to a screen of picture thumbnails, where the header is the name of the item. Whenever a theme change is detected, if
 * there are any installed snaps that don’t contain or link to that theme, and
 * the Snap Store contains a snap providing that theme,
then a “Change Theme” prompt should appear. (It doesn’t matter if the prompt takes ten or twenty seconds to appear.)
Line 19: Line 22:
{{attachment:phone-background-chooser-picture.png}} {{attachment:theme-snap-prompt.png}}
Line 21: Line 24:
Choosing a picture from “Ubuntu Art” should navigate to a “Preview” screen, because that art is already optimized for the screen size. Choosing a picture from any other source should navigate to a “Choose Area” screen, with a “Best Fit” button that crops the picture just enough for the remainder to scale to fill the screen. Either way, this screen should be unique in that '''the top bar, header, and toolbar should all be semi-transparent''', so that you can see what part of the background picture will be visible when they are not present. The snap icon, title, publisher, and rating should be presented the same way as on [[https://snapcraft.io/store|the Snap Store]].
Line 23: Line 26:
Choosing “Set” should set the background(s) and navigate back to the top-level “Background” screen, because its thumbnails display confirmation of what you’ve done. If you choose “Download Now”, the dialog should morph so that the question is replaced by a progress indicator, while the caption and commit buttons are removed.

{{attachment:theme-snap-downloading.png}}

The first half of the progress bar should be allocated to “Downloading extra theme package…”, and the second half to “Installing extra theme package…”. (This is the same allocation used for [[SoftwareUpdates#Installing|software updates]], and could be updated based on download- and install-speed metrics.)

If any error occurs during the download or installation progress, the dialog should morph to become an error alert.

{{attachment:theme-snap-error.png}}

If installation succeeds, and no applicable snaps are currently running, the primary text should change to “Installation complete” for two seconds, then the dialog should close automatically.

If any applicable snaps ''are'' currently running, the dialog should morph to display each of them with its own Relaunch button, plus “Skip” and “Relaunch All” buttons.

{{attachment:theme-snap-success.png}}

Clicking any of the relaunch buttons should send a signal to the relevant app(s) to close, and once they do, should launch them again.

If any listed app closes, whether because it was relaunched here or for any other reason, it should disappear from the list. If the list becomes empty, the dialog should close automatically.

=== “Background” ===

“Background” refers to the area behind all open windows in windowed mode, and to the welcome (lock) screen in staged mode.

==== Access ====

{{attachment:background-access.png}}

On the System Settings main screen, the “Background” '''icon should include a thumbnail''' of the currently selected background. Therefore, all the backgrounds in the icon should reflect the aspect ratio of the current display.

==== Structure ====

When choosing a background, by far '''the best representation is seeing the full-size background on the screen itself'''. This avoids frustration from choosing an image that has too low resolution, or from cropping an image poorly, and not being able to see the problem until you have exited. It’s also more fun.

Achieving this representation requires custom behavior in two ways.

First, '''each display should have its own Background UI'''. (This is unlike [[BrightnessAndDisplays|Display settings]], where all displays must be configurable on the primary display because a misconfigured display might not be working at all.)

Second, the UI for each display should let you see the background on that display:
 * In staged mode, System Settings should be '''full-screen whenever you are on the “Background” panel''', and the header should be semi-transparent, so that you can see the background behind it.
 * In windowed mode, '''all non-System-Settings windows should be transparent whenever you are in the “Background” panel''', so that you can see the background around the System Settings window, with only outlines remaining to reassure you that they are still open. As soon as you switch to another panel, or close, minimize, or unfocus System Settings, all other windows should resume visibility.

You can’t pinch or drag the real background to resize or crop it, so the windowed mode needs its own controls for that. Therefore, the Background UI must be different in staged mode than in windowed mode.

|| ||'''Staged mode'''||'''Windowed mode'''||
||'''The display that System Settings has been on'''||<^>{{attachment:background.wide.mini.png}}||<^>{{attachment:background.windowed-primary.mini.png}}||
||'''Any other display''', when “Different background on each display” is chosen||<^>{{attachment:background.staged-secondary.mini.png}}||<^>{{attachment:background.windowed-secondary.mini.png}}||

==== Staged mode layout ====

{{attachment:background.wide.gif}}

“New”, “Recent”, “Pinch to crop”, and “Drag to move” should all be white text with a black outline, so that you can read them against any background.

Tapping “'''New'''” should open [[https://docs.google.com/document/d/1trse15NokU8IJ5lm3BnUi7oMNTCkUnYNHeAHZdtzFoQ/edit#heading=h.woe7j0vyqk0u|a picker for selecting a new image]], including an “Ubuntu Backgrounds” collection (bug Bug:1288364) that does not appear when the picker is called from other apps. (Alternatively, this collection should be placed by default in the Gallery app.)

After a fresh install, the “'''Recent'''” list should should be pre-populated with the default images from the most recent Ubuntu contest. Otherwise, it should consist of the ten most recently chosen distinct '''background settings''' — that is, an image [[#rendering|rendered]] in a particular way. This means there may be multiple recent background settings that use the same picture but with different renderings. A background setting should be saved whenever you leave the “Background” screen.

If you '''choose''' a new image, that image should zoom up from the “New” button to be shown as the current background, following its [[#rendering|appropriate default rendering]]. If you choose any of the “Recent” items, that image should similarly zoom up from its thumbnail to become the current background. At the same time, any “Recent” items to its left should slide along one spot, making way for the previous selection to zoom down to become the most “Recent” item. If you chose a new image, the least recent setting should disappear from the list.

Long-pressing a “Recent” item should reveal a popover menu with a single item, “Delete”. (Deleting recent background settings will be a rarely-needed function, usually wanted only after relationship breakups.)

In the usual case where there is not enough room to show the “New” button plus all the “Recent” items in a single row:
 * The entire row should be scrollable horizontally. That is, it should be a horizontally-scrolling list spanning the screen, with transparent background and no border.
 * To indicate that there is more off-screen, the spacing between the “Recent” items should be expanded if necessary depending on the screen size, just enough that one of them is between 1/3 and 2/3 off-screen.
 * The scroll position should reset whenever you return to the screen (so that you don’t lose sight of the “New” button) or choose a different background (so that you can see the previous selection become the new most recent, and undo it if necessary).

{{attachment:background.staged-secondary.png}}

Whenever “Different background on each display” is chosen, on each other display a full-screen dialog should appear for configuring the background for that display.

## If “Different background for each display” is set and you choose “Same background for all displays”, the most recently chosen background should immediately be copied to the other screen. Conversely, if “Same background for both” is set and you choose “Different background for each”, the ''least'' recently changed screen should return to its previously set background, if that background picture still exists on the device, even if it was last used as a background months ago. (This allows easy undo of syncing the backgrounds.) If that background picture no longer exists on the device, the screen should change to its default picture.

## Whenever “Same background for both” is set, the welcome screen and home screen thumbnails combined should function as a single tappable button, navigating to a “Choose Background” screen. Whenever “Different backgrounds for each” is set, the thumbnails should function as two separate buttons, navigating to a “Welcome Screen” or “Home Screen” screen respectively.

==== Windowed mode layout ====

The windowed mode layout is different, so that it can contain a correctly-proportioned thumbnail for dragging.

{{attachment:background.windowed-primary.png}}

Similar to the staged mode layout, whenever “Different background on each display” is chosen, on each other display a parentless dialog should appear for configuring the background for that display.

{{attachment:background.windowed-secondary.png}}

<<Anchor(rendering)>>
==== Background image rendering: Tiled, Fit/Stretched, Cropped ====

Whenever you select a new image, its default rendering on each display should be whichever is most likely to suit that image on that display, but you should be able to change the rendering using a radio menu.

||'''Option'''||'''Enabled'''||'''Use as default'''||
||“'''Tiled'''”, with one tile exactly centered on the center of the display||If image pixel size is less than the display’s in either dimension||1. If image pixel size is less than 1/4 the display pixel size in either dimension||
||“'''Fit'''” exactly on the display||If image is at least as large as the display, with exactly the same aspect ratio (for example, exactly the same pixel size)||2. If image is at least as large as the display, with exactly the same aspect ratio||
||“'''Stretched'''”, scaled differently in each dimension to exactly fill the display in both||If “Fit” is not present||3. If image’s aspect ratio is within 10% of the display’s||
||“'''Cropped'''”, scaled proportionally at least enough to fill the display in both dimensions||If image does ''not'' have exactly the same aspect ratio as the display||4. In any other case||

<<Anchor(cropping)>>
==== Cropping ====

Whenever the rendering for the current image is set to “Cropped”, and you have a touchscreen or multi-touch touchpad, [[https://design.ubuntu.com/apps/patterns/gestures#application-gestures|the standard gestures]] should resize and pan the picture to choose the cropped area (bug Bug:1368286). In case you do not realize this:

 * Whenever you have been on the “Background” screen for five seconds without changing anything, the “Drag to move” hint should fade in and out over two seconds.

 * Unless you have moved a pointing device in the meantime, this should be followed by the “Pinch to crop” animation fading in and out.

 * Whenever you move a pointing device (indicating that you aren’t ''using'' a multi-touch input device, even if you have one), a “Size:” slider should appear instead, so that you can resize the image without pinching.

 * Over any non-control part of the screen (in staged mode) or the preview (in windowed mode), the cursor should be a grabbing hand, indicating that you can drag to move the image.

<<Anchor(launcher)>>
=== “Launcher” ===

||<^ style="border:none">||<^ style="border:none">{{attachment:launcher-settings.wide.mockup.png}}||

''Errata:
 * “System settings” should be “System Settings”
 * The intro label “Launcher appearance:” should be present
 * “Video and games” should be “Full screen videos and games”''

It is practical to persist or resize the Launcher only on large displays.

Therefore, The “Launcher” '''category should be present''' only when one or more display at least 90 GU wide is currently detected (for example, the built-in display). If you are on the panel at the moment that this stops being true (for example, on a phone when you disconnect the only external display), System Settings should automatically navigate back to the main screen.

In addition, the introductory label should be “'''Launcher appearance on large displays:'''” if the current display does not fall into this category (to explain why the settings aren’t applying to the display that you’re looking at), and just “Launcher appearance:” otherwise.

Clicking/tapping a diagram should function exactly the same as clicking/tapping the radio button below it.

Ubuntu desktop

A single “Appearance” panel should provide a setting for choosing a Yaru variant (Light, Standard, or Dark), and settings for the Launcher.

appearance-settings-2020.png

If you have any other themes installed (excluding the High Contrast theme), they should appear following the Yaru variations in the list, in alphabetical order, each with a generic theme icon (since theme packages do not provide any preview image). If any theme has an installed dark variant, it should appear as a separate item in the list (since that’s how the Yaru variants are presented).

Choosing any of the theme options should set the toolkit and cursor theme simultaneously. In the case where different themes have been set for toolkit and cursors (for example, using gnome-tweak-tool), a temporary option “Custom” should be present and selected as the last item in the list.

Whenever the “Appearance” panel opens, the list of themes should be scrolled, if necessary, to show the current selection.

Theme snap installation

Whenever a theme change is detected, if

  • there are any installed snaps that don’t contain or link to that theme, and
  • the Snap Store contains a snap providing that theme,

then a “Change Theme” prompt should appear. (It doesn’t matter if the prompt takes ten or twenty seconds to appear.)

theme-snap-prompt.png

The snap icon, title, publisher, and rating should be presented the same way as on the Snap Store.

If you choose “Download Now”, the dialog should morph so that the question is replaced by a progress indicator, while the caption and commit buttons are removed.
