Unable to organise favourites into folders and subfolders.

Currently the only way to do this is create a folder structure in the user home
directory under .netbeans\dev\config\Favorites.

Once this is done, the Fav Window shows the folder structure correctly.

You can also move links from one folder to another. This is fantastic and very
useful to organise and manage your folders.

But, via ui on Fav Window - context menu to "Add Fav" we are not able to 

 - create and add the link to a selected folder
 - create new folders etc.

Workaround is to create a Fav link and drag and drop it to a specific folder.

Please add this functionality

Not sure if this is defect of enhancement

Cheers
