[Bug 1488148] Re: windowed mode right edge spread selection needs animation

 

The current design is intentional for few reasons.

First of all the switcher view is visually quite heavy already. Maybe
not so much when accessed via edge push or gesture but in simple alt-tab
use case. Adding an animation, for example selected app moving to its
place, would be too much every single time you use alt-tab to switch
between windows. Also in that case we should consider the opposite
animation when entering the spread (surfaces moving from their places to
the spread) which would be superheavy and hard to implement nicely since
the z-stacking order is reversible in spread than in normal windowed
mode.

Secondly in the current design the spread surfaces are square to have
balanced look and feel and also enable nice looking stacking at the
ends. That means cropping of the actual window content to fit in the
square without stretching. Not sure how nice it would look to animate
that cropping between the states.

Thirdly, if the item that is selected is already the topmost item on the
desktop and animates its place when selected it means that the same
surface is shown twice during the animation. Unless we hide the actual
surface on the desktop right when the animation starts to avoid
duplication. This might be ok but we haven't tried it out.

If you have any ideas how to ease the transition a bit feel free to
propose.
