Matthew Paul Thomas, Canonical Design

Ubuntu contains System Settings on PC (gnome-control-center), based on my original design from 2008, and on phone and tablet. (For a summary of the design process on phone, see my 2013 article on the subject.) In line with the goal of a convergence device — not to mention, ordinary learnability and efficiency — these settings, and their categories, will be shared across form factors whenever practical. However, some settings will only ever make sense on one or two form factors.

This index does not yet include all settings panels included on the PC. It does include other things — such as version information — that, for want of a better position, are presented inside the System Settings UI in at least one form factor.

General behavior

Unless specifically noted, all interface elements in System Settings should update live to reflect settings when they are changed elsewhere.

Interpreting search text

Entering text in the System Settings search field should search category names, plus synonyms and other text as specified for individual categories.

Any word in the search string that is followed by a space or punctuation should be treated as a a complete word, while any word that is not should be treated as if it might be either a complete word or the beginning of a word (bug 1446086). (This is the same behavior as Ubuntu Software Center.)

should be documented here eventually, for testability and comparison purposes

Phone settings interface

Errata: • The search field should be present. • The icons should be in color.

“System Settings” should be an unremovable app in the Apps screen, and should be in the Launcher by default.

Whenever the search field is not empty, the rest of the System Settings main screen should consist only of those items matching the contents of the field. For example, if the search field contains “wallpa”, only the “Backgrounds” panel should remain. The search field should empty itself if you had switched to other apps for at least five minutes (because you have likely forgotten that you searched for anything).

If global in-app search is implemented, it should replace the System Settings search field.

Quick access area

The quick access area is a group of list items at the top of the overview screen. It should always contain items for:

Following those, it may also contain other items, in order:

All other items in the main screen should act as page stacks, regardless of whether they are list items (like “About This Phone”) or grid items (like “Sound”).

(bug 1488005)

At every level of System Settings, all page stack items — whether standard list items, or the grid items on the main screen — should have the same feedback for maximum responsiveness:

  1. When you choose an item, the item should highlight until its screen appears.
  2. If that screen has not loaded within two seconds, a placeholder screen should appear with an empty header.
  3. If the actual screen still has not loaded after another two seconds, a spinner should appear optically centered in the placeholder screen.

“Reset Phone”

The “Reset Phone” screen should begin with the text: “If you reset the phone, all files, saved games, settings, and other items will be deleted permanently.”

If you use any phone locking scheme, choosing “Erase & Reset Everything…” should first prompt you to unlock (bug 1388942).

Regardless, it should then display a confirmation alert (so that someone can’t confirm the reset and then leave the phone on the passcode/password prompt waiting for you to return, not realizing what the prompt is for). The alert should have text “Are you sure you want to reset your phone?”, and “Cancel” and red “Reset” buttons.

After the reset, you should be returned to the phone welcome screen.
