With auto-show enabled and sidebar hidden by default, having a lot of tabs and trees(for my m4 it's around 80 tabs total) takes a few seconds for a sidebar to show or hide.
I thought it could be because all tabs were loaded, but i tried to suspend all of them which actually made performance worse for a while but then it went back to the same one as if they weren't suspended.
Steps to replicate:
- Open a lot of tabs and make nested trees in some of them
Sidebar to open relatively fast
