I'm looking for a jQuery plugin / library that makes the contentEditable attribute work properly in all major browsers (I could even go without IE6). I don't need a full WYSIWYG editor solution because I want to build my own – however I'm focusing on user experience so I'd prefer a "plug and play" solution.
I only need to access the editor features through code (API-like), I'm building the user interface myself.
I ended up using WYSIHAT (http://37signals.com/svn/posts/1330-introducing-wysihat-an-eventually-better-open-source-wysiwyg-editor, https://github.com/37signals/wysihat).
It's Prototype-based (yeah, I know, not jQuery), but it's exactly the kind of "library" I needed. I can build my own toolbars and even own commands with ease.
jQuery can be integrated in .noConflict-mode.
Tinymce allows you to build the interface yourself and is jquery compatible.

If you desire to build everything yourself(like from scratch), there will probably be a lot of cross browser debugging needed. Some browsers like IE support exexCommand others don't and you now the typical javascript bugs that come with developing a library.
I would just delete what you don't need of off tinymce, if you want efficiency and speedy.
