Can you save the image?
An undo button would be nice... :-)
What does the +/- buttons do?
Also when closing the application it complains about unable to run script.
1. Not currently
2. I could look into that as well
3. Pen size changing
4. This error is because I forgot to implement the sys module in python, I'll be sure to fix it whenever I can
Thank you for the comment :)
