Just got back into ArtRage after a 2 year LOA. I could use a jump start with my Iphone and IPAD app development.

I am creating buttons on my app, and I would like to be able to make custom GREAT-as-only-ARt Rage-can-do-buttons. Example: The cooper sticker has a perfect square number (8) which I can use.. if I can figure out how to change the color...

how do I change the color?
How can I make my own buttons, including rectangular buttons?
Has someone else done this and is this an API sticker set - or similar???

My prior Art Rage was simple black and white pen to create editorial cartoons.

Also, any help on making launch icons, retina icons, etc.. would also be appreciated.
