Love this tool but its lacking in just a few things that make this tool usable on a daily basis. Im a web dev, game dev, and programmer and would use something like this to keep my adhd in check. I wanted to list a few features that I would like just in case you guys were taking suggestions. :)

1.  Line numbers displayed
2.  Font size adjuster
3. Find and replace tool
4. Tabs for more files

I agree! I want to show this to one of the kids I work with (he' loves letters!) and I really want it to be a lot more user friendly. It's okay if I would be able to help him, but I would love it if was something he could do on his own. I'd also like it if there were more fun sounds to it.
