I'd like to see a progress meter or at least a total time for the track.

Fitting it into the display is the easy bit (except possibly in Info: Line). A bigger problem is how to drive it -- ideally there'd be a button on the remote for elapsed vs remaining vs "elapsed/total", but the remote UI is pretty densely-packed as it is.

Time remaining and "elapsed/total" on the current playlist would be harder but much more cool
