Yes, I think this is an excellent candidate for a suggestion that has very strong chances of actually being implemented. Mainly because it is very easy.
I'll submit that request ASAP.
Shortcuts for changing between animation would also be quite easy to implement, but I am not sure what should they be? Any suggestions?
I've noticed that plus (+) and minus (-) are undocumented keyboard shortcuts to cycle through frames of the current animation; maybe repurpose those to toggle through animations? Or perhaps ctrl-(+) and ctrl-(-)? Really anything works, you're the expert.
