Manga Studios

[ProphetGirl16]

Hey everybody!
I've noticed that a lot of people use Manga Studios on here. I have one too, but I don't know how to properly use it, so I'd like to learn from the pros! ^o^

Here come the questions!

1. When you import a picture, you can erase some of the original drawing without having to delete the whole picture; is there a special setting for that?
2. How do you make frames?
3. Is there a way to use screen-tones to shadow colored pictures?

More questions will be on the way (as soon as I think of them).
Thank you!
