Thanks for helping, Wedrownik!
Yeah, it could be a bit more clear, though the symbol language does resemble Blender's. (I wasn't part of the design process on that but it was one of the things that immediately made sense when I first started using Spine)
If you have a chance, take some time and press F1 while hovering over items you don't understand in Spine. F1 makes the tooltip appear immediately and we tried to write it so it can explain what might not be clear at first glance.
We'd also appreciate it if you tell us if something's too vague or obscure.
We should probably also tweet these little helpful things, maybe. :p
