- Horizontal space is at a premium, so don't show line numbers. When scrolling, show the line numbers hovering over the lines (so I can find my spot in a long file if I need to), but I don't need to see them while actually editing a line.
There's no access to the filesystem in iOS Safari, no uploading or downloading files.

It almost works with Android, except for the special-characters-menu, the tooltip of which gets hidden under textarea.
I would happily pay for this app.
