Sorry if you have heard this before, but I had a small back and forth with Hans Goudey about the outliner:
I was saying that it might be nice in the future if we could click on the modifiers in the outliner and have the modifier tab open and close all modifiers except the selected one. Hans thought it would be cool if it would auto scroll to the selected modifier.
I realize this is closer to properties syncing which is already finished, but I wondered if this could be a consideration? I know the to-do list is already pretty big, just curious.
