Favourites Dialog Options

Just wondering how much you can actually do with the favourites dialog, for example can you use anything other than ListItem.Label? Also is it possible to have differences based on the type of favourite (e.g. movie, tv show, music, etc).

I'm trying to move the context menu based on the type of media, it currently looks fine for movies...



But for music I would like to move it down to sit just above the album artwork...



Is this possible? I thought I might be able to do it using the DBTYPE but that doesn't seem to fill in this dialog.

Thanks in advance!
