Not part of the jam at all, just stumbled across this. It's neat! Haven't yet finished it, though.
I wish the terminal had a little bit more of that standard terminal UX that I'm used to - up arrow to filter back through previous commands, tab to auto/partial complete filenames, being able to use `folder/filename.txt` type syntax. That sort of little polish would definitely step it up a few notches, but I understand that it's not necessarily easy to do under a time crunch!
