Remember expanded and collapsed folders

This is more of an improvement than a bug.
It is a few extra steps each time to open the root folders again after pressing the compass button and returning back to the Manage Folders tab.

Ideally, the app remembers the expanded and collapsed folders and displays it when the user returns back to the view

Start in the Manage Folders tab and trace the folder tree state when the compass button navigates away and the user returns. Confirm how expanded and collapsed folders are currently represented, then verify that returning to the tab restores the same arrangement shown in the issue video.
