The thing I like about Komodo is the graphical debugger which even works for threaded Python. As an editor, it is okay and has the useful feature that it's interface is very similar on Windows, Mac, and Linux (it's built using Mozilla's XUL).

It looks promising, I am going to try it out, see what features it has. Can you give any more description on what you like about it and what language you use it for?

EDIT: Maybe I am missing something, but this seems like a regular text editor with no nifty features like code outline. What does it actually give you over something like vim?

I used Komodo Edit on and off. It does have code completion in some languages (my experience is with Javascript). It also does code folding, among other things.

I found it to be generally useful, and the mixed mode syntax highlighting work well (actually, for my situation, it handled it better than any other editor). It isn't as fast as other editors, though. The project explorer can be particularly slow.

There is a paid Komodo IDE - I believe the free version is only a basic text editor.

I use Komodo for Python, but find it hit and miss. Still looking for something better.

There is a limit to what any editor can give you for any language that's not amenable to static analysis.
