Hi,
A nice feature would be the ability to select multiple bones (or any other item), then give it a name like:
"tail_bone_1", and all other selected bones, will get a sequential name according to their selection order,
so spine will automatically will name them tail_bone_2, tail_bone_3 etc..
if there's already an item with that name, it will just try the next number and so on..
I find my self spending a lot of time renaming bones, the search and replace feature is great, but sometimes
simple mechanism like I described is very helpful ๐
oh and another feature to rename directly in the tree view, maybe by using F2, would also be a time saver imo ๐
