I really, really like this idea, however, it has some issues (Maybe just me. idk). I guess the main issue I'm having is that the controls aren't user friendly. For example, it would be really nice to be able to erase by simply right clicking on where you want to erase. Perhaps include a erase part of a line, so that you don't have to erase the entire thing each time you want to make a small adjustment (plus, alt+o is on the wrong side of the keyboard for me). Another issue I have with it is the fact that it is very laggy. And seems to take a while to do anything. I really do like this idea, and think you're off to a great start, but I only wish it was easier and cleaner/faster to use.
