I absolutely love that you can change colors, and it saves the last few youve used!! I love that it has an erase tool. Three things that I would love to see, is the ability to select a portion (or the whole thing) and move it about the screen; a zoom feature; as well as a brush size (I find the brush size getting bigger used on a space that already has colour annoying). The only thing I am not fussy on, but complain, but say it anyways, is that I am using an iPod touch and the screen is so small!! Thanks a lot, and keep up the great work!!
