A scripting system for snap shots would be handy. The ability to dump an interactions snapshot stack, make edits via s text editor and reload into the interaction.
I haven't seen it mentioned anywhere so I'll just toss this out as something to think about.

The real advantage to a script would be in very fine tweaking of expressions, force values and the like. A user could also make a library of quick cut actions and tranistionals that would otherwise be tedious to duplicate for every new interaction.
Not a big deal overall but if you are having trouble thinking of new things to put on the roadmap, scripting may be worthwhile.
