Only had one service where it was off the whole time, but currently it doesn't show the status of how busy each coach is in the core. Until that is sorted, it does lessen the usefulness somewhat.
I also think going forward, it should perhaps stop showing the TfL information once going away from London, say once beyond East Croydon or Elstree & Borehamwood?
Come to think of it, going forward, I'd probably use the same width font but squash it down (but within the regulations) so there could be an extra line to show fixed information - such as what coach you are in, the time, weather, what class it is (and if it's declassified) or whatever it can do.
