Text editor

I'm getting tired of Notepad++ and its annoying and cumbersome interface. I'm looking for an editor with:
1.Syntax highlighting/+User-friendly way to edit highlights bonus
2.zero cost/+Open source  bonus
3.search and replace:in selection/+regex bonus
4.Multiple document interface/+tree view bonus
5.Code folding or equivalent./+Auto-completion of keywords/brackets/functions bonus
6.Ability for changing font/colors/appearance freely .
7.Ability to handle unicode and large >64kb files.
8.Extensive undo/redo /+bonus for keeping it after saving.
9.Macros or scriptable commands.

Komodo Edit might be what you want. It's free (as in beer), comes with a bunch of different syntax colours out of the box, has support for Firefox-like extensions, and has fairly auto-completion for dynamic languages.
