One thing Maps has which Drive lacks (in my opinion) is ordering favorites by distance (Drive orders them by modification time, so it is pretty difficult to find the right favorite by swiping through if you have more than a few). I had a look at the Drive QML code a while back trying to change it but did not succeed so far.

There are some references in the Maps QML about favorites, but I could not find a place where the ordering was set or explicitly reordered on a quick look.
