Could we please implement an option to adjust the cabin lights brightness from the flightdeck EFB. I don't generally go back into cabins, (I don't even know how to)! I understand I can only adjust from the FAP at the moment and I just cant get back there. My first flight was a night flight from EGLL to OMDB and I could not see any cabin lights in the external view, other than that I'm loving this plane just as I do the A350. thank you so much for both. Best regards. Malcolm Hancock.
