Ive been wanting to have some feature to tilt the canvas, and Im glad you did. It helped me draw curly lines because last time, they look a bit squiggly (I dont know how to really explain) So far, few crashes has happened to me. A few bugs that I have found was that sometimes the screen flashes a bit and it resets the line you drew or the spot you erased. I dont find it as something very major, but it can be a bit annoying to me, so if you can fix that Ill be very pleased. One thing I want to know is how to save your movie of drawing your painting. Not uploading it. Just saving it on your camera roll. If you could make it an option, I would love that. Also, the option called, "Artwork JENPG" or something like that, Ive been emailing it to myself hoping that is how you save the movie on your camera roll. However, it only says the title of your painting and nothing else. I dont know what JENPG means, but I havent read most of the description. If you can make an option to save the movie of your painting into your camera roll, Ill rate this 5 star because its the app that I have been using for one year that hasnt caused many problems. (Of course, there are the bugs)
