I still like Flickbook better, but since I like making animations, I had to give this a 10...

These are the differences between Flickbook and Animanatee:

Flickbook has:

Zoom
Canvas moving
Different Brush Sizes
Onion for frames in front of it
Multiple Onion Layers displayed at once
Copy & Paste feature

Animanatee has:

Custom color maker (Up to 32 Colors can be stored)
Bigger frame
Better design
Pointer so you know where your stylus is before you draw
Fill
2 Layers (Background and Main)
Change framerate
Scroll bar
Undo/Redo


Basically if it had "Zoom" and "Canvas moving" (for precise drawing control), this would be like a very basic version of Flash animation. Also, it's those 2 features that make Flickbook really good.
