This has been mentioned before as an issue, but I don’t believe its been made a wish list item, so here goes.
When you have multiple people working on one board, having everything locked works great. When you’re alone on a board, the “unlock all” is also great.
BUT, if you are working with others on a board with a large group of locked items and need to unlock just one of them, the only practical way seems to be to tell everyone to “WAIT” so you can “unlock all” do what you need to do, and then re-lock everything….not the most helpful situation.
Keeping this one alive. I’ve seen other threads about it and I’m sure there must be others with the same wish.
