A "Drawing Board"
I came up with an idea! There should be a place on the site called the "drawing board" in which you could sketch out ideas using your mouse and save them as a JPG. You could incorporate this into drawing plans and designs for your instructable! It could be a cool feature for everyone, but for pro membership you could have extra things (e.g. rainbow colors, a ruler, paint brush mode). I think this would be a cool addition to the website.
