So here it is :D
But please be carefull it's still a beta, but the most stuff should already work. Known problems are with Drag and Drop (some of the tree stuff works).
However it is a tabbed version, just for the web at the moment and just tested on Chrome and Firefox.
Please report any problems to me:
- Get in contact on the homepage
- Post a comment here
- Post a bug at the google code page
If you already want have the source you just can copy it from there, but it isn't minified at the moment :)
At least the link:
Start the editor in an popup (just click on the link)
