I use stacks to manage bracketed pictures and I often want to collapse all stacks in the current scope (version and normal stacks) to clear up the file window.
Unfortunately there's no dedicated button to toggle all stacks, i can only show/hide already stacked files.
I know i can use Ctrl + A, T (for Version Stacks) and Ctrl + A, Ctrl + left/right (for normal stacks), but i think another Button would make it easier and fit well with the "Show/Hide stacked files" button.
Thanks :D
PS: Why are version and normal stacks distinguished from each other?
Version stacks are automatic and dynamic. Normal stacks are made by users. Both serve slightly different purposes.
The Ctrl+A collapse method works just fine I believe.
Note that you usually can keep stacks closed and just let the File Window show them expanded when needed (toolbar button).
I also recommend to separate questions about features from feature requests in the future.
Mixing answers to questions with comments about the feature request may confuse things.
