Since the items in the tree automatically get sorted alphabetically (which usually makes it a mess and not any easier to navigate) I've decided to resort to using various punctuation to get them into the order I want and to make it visually scannable. (I have a lot of bones that overlap or are too close together to reliably select in the viewport.)
Are there any restrictions I should know about? If I use things like + or * or /, will my computer explode?
(I am so frustrated with Spine right now. I don't even... deep breaths)
