Got a couple problems that might be bugs or maybe I just don't know how to do it and cant find any docs or forum posts that tells me how.
1: When duplicating an animation the duplicated animation works but the dopesheet is empty for every bone/slot. The orange diamond shows in the timeline but it does not show the animation slot on the dopesheet so nothing can be edited. Save the project, restart spine and everything appears how it should.
2: When spine is first started and you enter the animation section you can see slots on the dopesheet for all bones & slots. This is handy to see exactly whats going on but once you select an individual bone you see only that bone on the dopesheet and there appears to be no way to get them all back together. I thought selecting the root or skeleton would show them all but its blank. Closing and reopening spine seems to be the only way, until you select and individual one again.
