I apologize if this has been answered before. I searched for ten minutes, but couldn't find the answer.
I've figured out how to save custom canvas sizes so that they can be picked from the popup list. However, I can't seem to find a way to set one of them as the default. It's terrific that Artrage gives you a fresh canvas on startup, but if it's not the size you want, you have to start a new one anyway.
Any help will be appreciated,
