Great idea! I could see that coming in handy. I have about two dozen lists and I try to keep them collapsed when I’m not actively using them, but I’m not so diligent in practice so it’d be nice to have a quick shortcut for that.
What keyboard shortcut(s) would make the most sense to you? Put another way, if you were to try a couple shortcuts to see if they did the trick, what would you try?
(I’ll probably end up adding a button you can click as well, but I wanted to get your hot take on the keyboard shortcut right off the bat.)
Being able to put lists into categories/groups, which could themselves be collapsed, is another feature request that could help here. (Discussed in this thread.)
