So I just started using this program last night (I've never so much as touched a digital art anything before) and by today I'm finally starting to at least show some progress.

Here's the thing...there is a lot of stuff I have no idea how to do and searches don't seem to pull helpful info up...

I was drawing something and I saved it so I could take the dog out and when I came back to continue drawing, I could not alter the drawing. I figured there must be some kind of edit function but they've hid it well among all the buttons and tools :/

Anyone know how to edit a saved drawing in this program?
