I have used many animation software packages, including TVPaint Pro, (which I love), however the new Animation Paper alpha is extremely easy and intuitive to use. I really like the performance. I like the way you can insert frames and the output is great! The only bug I noticed so far, (I am using a 22″ display monitor with a stylus) is that the cursor is hard to see or find on screen, when I go from using the stylus to using the mouse. I can hardly wait to use the full release software when it is ready!
