JQuery's WYSIWYG ... Please, need advice.

JQuery's WYSIWYG ... Please, need advice.

Hello,

I am looking for a lightweight WYSIWYG editor based on JQuery if possible.
Is the one of this forums available anywhere?
And what other options do I have?

I would like something lightweight and customizable (with CSS) both in appearance and functionality.

By looking at this forum's WYSIWYG the only new features I would need would be:
1. See the Html code and edit it in a popup window;
2. Define a Header tag;
3. Localized.
4. And maybe maximize it.

I have been using TinyMCE. Is great but really heavy.
Every small implementation takes ages because I spend to much time looking at TinyMce's code because it is quite extensive.

Please, tell me that this editor is based on JQuery and available as it is ...

Thank You,
Miguel
