I wish there was an option to clear a page that you've started but then realized that you really do not like the way the image is turning out. Right now I can back out of the image them re-enter the image selecting start over. But that saves the image you don't like and ends up filling the 'my works' tab. I have 200+ images that I started and decided the colors I thought would look good together of that image really don't work well together in that image. I also tap the back arrow to remove the last areas that have been colored. But tapping the arrow 50 or more times is extremely tedious and frustrating. And many times the arrow returns to the shaded grey color leaving some areas colored. This becomes even more frustrating because I just tapped to remove fillings for what feels like an eternity, and I'm still stuck with a partially colored image that I really don't like in the 'my works' section.
This is a must-have feature. In a painting app that encourages experimentation, it is currently a real drag to have to leave the painting area to “start over”.
A CLEAR and a RANDOM button would give so much more room for exploration.
