The save button seems counter intuitive. I dont know how many times now that I have had to redo a pose because I have hit the wrong directional arrow. I do enough web work that I read the up arrow as save and the down arrow as download a pose from memory into the workspace. Noooo! It really pisses me off that the pose is completely lost and I have to start all over. Even if there would be an undo, that would be better, but one touch and all my work is gone. Other than that, the app is fine. But that one UX issue is annoying as hell.
