About line numbers -- the people of TYPO3 did add them to their branch (though they made a bit of a mess in the process), and it seems most other in-browser code-editors support them, but I've never really seen their utility. Something like a status bar showing the current line would be just as useful, less wasteful of screen space, and addable as a wrapper to the current editor. I designed the thing to be a 'component' that can be put into all kinds of systems, rather than a full-blown IDE.
