I agree however you forgot to mention the excellent Geany, which looks more comparable, and I think it be better for a developer to spend time improving that rather than porting a heavily MacOS based editor.
Indeed, we already have things like Emacs, Vim, etc. But this is not Windows, not Mac. This is SPARTAA^W GNU/Linux and there people should have freedom of choice.
Exactly. For those who dont't like the learning curves of these editors, there are easy to learn and well designed editors like Sublime Text, Bluefish, Geany.
