Maybe been mentioned elsewhere that whilst I fully support Bluetooth control and all the bells and whistles I simply do not want to spend my hobby time using yet another screen. I just want to switch off from electronic faff and stress! So an analogue type traditional control for speed and direction but retain the screen for all the luxuries! The traditional type controller would be linked by hard wire or Bluetooth to the iPad and would simply be a different, simpler user interface for those who want it. Of course, being new to the modern day world of model trains ( thank you TT120 ) it’s possible that I’m missing something and that my idea is already possible.
