Open Cell Animation
Animation Paper supports the OCA format. It's an open format, that eases the exchange of hand-drawn animation between different applications - both commercial and free.
OCA holds the vital x-sheet info like layers, timing (exposure and reused drawings), color, transparency, framerate and more.

If those of you with a little technical wizardry happen to create (or know of) any conversion-scripts, Add-Ons or dream up any other clever usage for the OCA format, please let us know. We will be happy to include info about it here.
