Hello! 
I found this project a few days ago, and it’s pretty impressive, by far better than the animation program i was using before (Flash lol). There is one thing that i would really like to see here: an object layer, or something like that, that has an image with transform (position, rotation and scale) that can be setted in the keyframes and be interpolated between them. That would be a really nice tool to have in the program.
Sorry my english, i am a spanish speaker.
