Stickfigure Anim8er version 4.0 is releasing within 2 months! With great new features like onionskinning, custom characters, and motion tracking, you will have the expert animation suite! I am also trying to deal something out with poses so that there is a button you click and boom-they are in a list you can export. Then in Stickfigure Animater 4 Collection and up, anything can read them.
