Create a Collapse All Layers Button
Currently you can collapse (or expand) all sub containers by Alt key clicking on the little arrowheads on the left-hand side of the top level container items. It would be great if we had a button we could click that collapses (or expands) everything.
Bonus points if this could be called by an action or script!

Another bonus point for having an assignable hotkey for that :)

This is just simple common sense.
