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.

Mac-Only software. Also:
TextMate does have a few limitations:

    * There is no support for variable-width or wide fonts, meaning that languages such as Chinese, Japanese, Korean, and others are not really supported, as their characters are wider than Latin characters.
    * There is no right-to-left support for languages such as Arabic and Hebrew.
    * Large (many megabyte) files or long lines (many KB) can slow TextMate considerably. Other editors have better support for large files.
    * TextMate has no built-in support for (S)FTP. There are some workarounds mentioned at the TextMate Wiki. [15]
    * Because TextMate is not tightly coupled to a scripting language, as Emacs is to elisp, it is impossible for users to have complete control over the behavior of some built-in commands such as those which indent sections of text or those which move columns around; however, almost every useful action can be accomplished with TextMate’s macros and commands. Allan Odgaard explained his thoughts on the subject in an email to the TextMate mailing list.[16]
    * No built-in HTML validator — because TextMate uses the W3C validator for HTML validation, users must be online to validate HTML.
    * No support for split views
