A service to manage a box.net account

I have just uploaded something unusual for my website. It is not a sample , its a web 2,0 mini-app
that helps manage a box.net account. If you don't know what is box.net just follow the link to see.
Features:

1. Drag and drop move files
   
2. Rename files/folders by double clicking the node and editing the value
3. Download files from your account
4. Delete files/folders
   

Planned features:
Upload files (that was working like a charm in my dev environment ...but its not working in the remote site).
This isn't a sample , cause I am not releasing the source-code.
Don't be fooled by the app speed ..its really updating your account.
