I know that for now you can have a bone to each part of your asset, but it would be super usefull to use more bones in one asset to have better control of the movement.  On this Cape animation bellow I've used the water effect: (it's a subtle 3 frame anim)

It would be awesome to do something like this to have better controls, even on the tip of the cape.

So far, I'm loving this App, keep up!

Thank you for the suggestion, of course, should be really useful, it's planned for future update ! 

Thank you, I will update this post when it will be up.
