I am glad to hear that!
You bring a good point on the other thread, and I can see how this could be useful to be used on other tools like Spriter. Exporting individual parts, while seems like simple enough, it is easier said done. We have to change a lot of things to get it working that way.
But I was thinking overnight, and I might have an idea on how to do this (well, more of a compromise, really). What if, we add a new animation / pose with all the body parts blown up / separated? something like this (just a preview, of course) :
Then you can export them to PNG!
The only downside is, depending on your tools, you might have to slice them up per parts manually using image editing software. What do you think?
