1) I'd like the titles to be Markdown-friendly headings instead of C comments, personally.
2) I'm not sure if this is within scope - maybe this is just something to do on my own in Dropbox - but it would be neat if there were an 'archive' button. Let's say I'm done with one of my files and I want to clear it out. Push the button, and that file would be moved to archived/DATETIME.txt or something like that, and cleared.
