Changing the Folder Tree

Is it at all possible to customize the folder tree's appearance beyond the options given in the preferences? Basically, what I would like is to have some spacing between the grouped elements, as well as the ability to change the order in which elements appear (Libraries, Computer, Favourites etc.)

Is this possible somehow?

No, not currently.

Sorry for the long delay and thank you for the quick reply. I guess I have to keep my fingers crossed for a feature update then.
