Thank you! I’m happy you like Animation Paper!
Actually most of what you wish for will happen while we are in alpha stage.
The distort option we didn’t plan to do, but it is a good idea, maybe we’ll do that some day. But what we did plan for is a squash and stretch way of scaling/distorting. So you can stretch or squash your selection in any direction and it will do the opposite squash/stretch accordingly in the perpendicular direction. I mean, if you make it longer, it will automatically become thinner and vice versa (keeping the volume of course).
