It's a good app, but... – FlipaClip: Create 2D Animation Review

So I do like it. It's easy to use and usually gets the job done, but most of the time it gets me so frustrated I had to take a break. I was recently trying to make my animation, and I accidentally filled my picture a bit too much, so I pressed the undo button. But it wasn't working. Then, it crashed, and the entire frame that was taking me about 30 minutes to do, was gone. And when it doesn't do that, it constantly keeps crashing. I really would appreciate the bugs being fixed. Thank you!
