is there a way to sort animation names in spine editor? similar to how you can rearrange stuffs in photoshop layers.
so similar animations can be kept together neatly?

right now we have to rename the animations adding some numbers to let them sort together

They are sorted automatically but you can use folders to group animations (and skins and events). Note at runtime that the folder path is prepended to the animation name in Spine. For example, if folder 502 has animation TURN-LEFT then the animation name at runtime is 502/TURN-LEFT.
