Improve companion app utility

As many here have attested, trying to use the Apple TV remote (or its proxy on the iPhone) is terribly frustrating.

I would like to see the companion app take over from the login screen for a number of things:

  1. choosing workouts
  2. connecting to devices
  3. choosing worlds
  4. changing between worlds mid ride
  5. stopping and starting workouts or swapping from racing to free riding etc. without having to re-login/pair devices
