Bookmark module with a dhtml library

Hello,

I wanted a user-friendly bookmarking system in combination with drupal authentication and I had some fun with Ajax en passant.
And I absolutely wanted to have drag and drop one way or another so that's why I used an external JS lib. :-)

Take a look:

Just so anyone asks why I did not theme it: just wanted to have a small window with nothing but a tree in it.

I would like your remarks and/or suggestions on this. And if somebody finds it useful than all the better.

Greetz,
Philippe.
