Small, non complete list:
Nav Lights brt/dim: add "Nav Lights Brt else Off" and "Nav Lights Dim else Off"
"Toggle Landing Lights switch" and "Toggle Taxi Lights switch": add "Landing Lights On else OFF" and "Taxi Lights On else OFF"
Master Armament On/Off: add "Master Armament On else OFF"
Toggle fuel transfer switch: add "Fuel Tansfer Pyl else Tip"
Toggle Windshield demist switch: add "Windshield demist switch On else Off"
Toggle Rain RMVL: add "Rain RMVL switch On else Off"
Toggle Navlights flash/steady switch: add "Navlights flash else steady".
Toggle beacon light switch: add "Beacon Light On else Off"
As a general rule of thumb, might be great if:
For controls that can be toggled between "On or Off "(in general between "A or B"), please add a "On else Off" ( "A else B") bind.
For controls that can be changed between "X <-> OFF <-> Y" (between "X <-> Z<-> Y"), please add "X else Off" AND "Y else Off" ( "X else Z" AND "Y else Z") binds.
Toggling is perfect to use when you have to deal with push buttons. However, most HOTAS sticks have 2 or 3 way switches, which whould be perfect for these kind of controls, provided we have a "X else Y" bind scheme
My english is not as good as I wish, so I hope this is clear enough for you to understand what I mean. In case just send me a PM (in Italian ).
Also (I almost forgot): please, add controls to rotate the Heading and Course knobs of HSI.
