I've always wanted a feature to toggle on and off whether pre-comps in a master comp will "open in place" in that tab in the timeline. I find scrolling through all the comps at the top of the timeline is messy and frustrating when you are going in and out of pre-comps often.
So my suggestion would be if a comp is opened from the project panel everything that's opened from inside there stays in that tab. That way if you do want that comp open you can do it from the project panel but it doesn't create unnecessary clutter.
Premiere Bins have a similar functionality where they can be "opened in place"
Then there can still be an option to make a new tab from that pre-comp if you right-click and make
one but the default setup is "opening in place"
Maybe I'm the only one but that would make me happy
