I set the Customizable Buttons of the Spark RC Fn = Cammera Up/Down and the trigger to Gimbal FPV/Follow.

What is the setup do you have in those buttons?

Maybe DJI can add other more usable functions, like orientation lock, altitude lock or mode switch (for example FN to activate the gesture mode or active track)?

What do you think?

very good idea , fingers crossed they are listening
