Does such a text editor exist?

I am looking for a decent text editor that has the following:

- Tabs for open documents.
- Tree view side bar.
- Syntax highlighting for major languages.
- Line numbers
- Intelligent auto-formatting*
- Persistant code collapsing (so if I collapse code and then close and open the same document, the code is still collapsed)

Preferably:
- Able to login to my server via SSH and edit files directly on there.


* I want it to format my code/text such that if it exceeds 80 characters it puts the text automatically on a new line and indents it automatically. For instance if I was doing HTML:


...I'm now editing that sentence and it will be longer than 80 chars so it does this:


Or if I was doing javascript, this:


would go to:

I'm not sure if it meets all of those requirements but have you looked at TextWrangler? I know that it meets at least half of those.

You might also take a look at Smultron 4 in the Mac App store. Version 4 is only for Lion but there are earlier versions available if you're using Leopard or Snow Leopard.

I'm willing to bet that you could do most of that with Vim and a well designed vimrc file. The little bit that you can't do with vimrc can probably be accomplished with Vim commands. For instance, here's an example of doing code folding.
