[dash] does not remember the user's fullscreen preference

[dk]

Steps to reproduce:
1. open the Unity 2D dashboard or click on the 'Applications' or 'Files & Folders' lenses.
2. if your native screen resolution is 1280x800 the views do not open full screen. (this may be by design. please read further)
3. click on the icon in the bottom right hand corner to force the view to full screen.
4. close the view (clicking the ubuntu logo in the top left hand corner will accomplish this)
5. repeat step 1. the views have returned to their default state (not full screen)

Expected behavior:
When I tell Unity 2D that I prefer the dashboard or lens views to display full screen (by clicking the icon in the bottom right hand corner) I expect that subsequent visits to those same views maintain that preference in the same way that Unity 2D honors both the 'Shortcuts' (on the dashboard) and 'Refine Search' ( 'Applications' or 'Files & Folders' lenses) options when they are re-opened. Why is the full screen behavior different than the others? It shouldn't be. It's EXTREMELY frustrating to have to force Unity 2D to take advantage of ALL my screen real-estate EVERY single time when I use the views.

Proposed (recommended) solution:
Have Unity 2D store the full screen state of the dashboard or lense view when it's closed. The next time the user opens the view Unity 2D can check the previous state and restore it instead of resetting to it's default. This could be accomplished as easily as checking a key like "dash_fullscreen = 1". Similar to the other options mentioned above this preference should last the entire session until I log out.

Proposed (long term) solution:
A native Unity 2D (user configurable) settings page with a checkbox for full screen preference. If this solution is chosen it should persist permanently and the preference restored among multiple sessions as well as reboots.

Asking for feedback from design team. IMHO the "Proposed (recommended)" solution is good enough, but it would be great to hear designers' opinion as well.

This 19" widescreen user thinks that the Dash should permanently open at the size the user has set as a personal preference.

Personally I agree with DK's proposed solution as I too am fed up with always having to click on the expand button in the lower right hand corner to force it to full screen.

Note:
I find that a near instantaneous eye-scan of the alphabetical listed Apps in the full-screen is quicker to use than using the category filter.

We could test how users react to having it remember it's size. So if you
maximised it once, it stays that way through subsequent invocations,
till you restore it. What do you think?

The Dash mode is already stateful in Unity3d, so marked as fix released for this project.

That was fixed in Unity 2D by commit 875: "[dash][panel] Refactor testing for forced dash fullscreen based on resolution into DashClient."
