This is somewhat minor, but I’ve been meaning to add this to the wish list for a LONG time!
When the trigger menu is open - any time you open/close a group, the viewing is reset back to what was last highlighted. Most often, viewing resets to the top of the layer list because that is the default.
This small reset breaks the flow of setting triggers quickly, and if you have many group layers within each other, it can be a hassle to keep navigating to your original place.
The expected behavior would simply be to not change the view at all when opening/closing groups. I created a video below to better describe it : https://www.dropbox.com/s/3neuk9ce8kasg5t/TriggerMenu-ArrowsResetViewing.mp4?dl=0
