The TinyMCE replacement that is tinier, more flexible, and just plain awesome...
Classic Moo!
* Tiny - Under 16KB compressed & gzipped, under 500 lines.
* Customisable - Each instance can have its own layout and buttons.
* Multiple Toolbars - One bar for all, or all for one...
* Floating, fixed or inline - Should the editor be in the page flow, or above it?
* Skinnable - comes with a few ugly themes, add your own.
* Flexible - easily extended to include any button or element you can dream of.
* No i-frames! - Smaller, cleaner, trendsetting. Loads of benefits..
* Inline editor - Natively handles true inline editing
* Modular - In true Moo fashion, get your custom build, and shed the extra 2KB
* More - But you're getting impatient. Keep your eyes open, there's more all around...
