I’m looking to invest into making a somewhat more realistic flight sim (just a switch box) because my computer can’t handle flight simulators, so I think it would be great if you could add more assignable buttons (for instance VNAV, LNAV, APPR, ALT, HDG, Speed toggles) and also the new autobrake system (assignable for a toggle but also able select levels {low, med, max})
Other possible ideas for the assignable buttons:
Trim Axis (for trim wheels)
Engine One start, Engine Two Start, Engine Three Start, Engine Four Start
Seatbelt/No smoking lights
APU Toggle (Toggles Start/Off)
Main Battery Toggle
