Add Collapse All-Button next to Expand All-Button
Problem to solve
For longer MR, you can't find beep and the UI is slow as blank. It takes forever to collapse all files and you need to redo it every time you need to reload the page.
Proposal
There is a Collapse-All
-Button next to the Expand-All
-Button.
What does success look like, and how can we measure that?
You can collapse all files in 3 seconds instead of one minute.
