Use case or problem
Publish UI shows all files (Changed/Unchanged/New) as open folders. There is no quick way to collapse (or expand) all folders, so you are left with manually toggling folders open or closed.
Proposed solution
Include an option to quickly collapse or expand folders, similar to the Collapse All community plugin which targets the core File Explorer.
Current workaround (optional)
Lots and lots and lots of clicking or scrolling!
