fave things i have programmed:
macros for salvo and delay, can set them pretty much instantly, big help when you realise your salvo is set to 1 moments before you need to drop on that CV or HQ lol.
wheelbrakes ssigned to bands on the mouse, throttle 2 on slider so i have differential engine control while flying 38s, mossies and things like that, it makes for brilliant reversals hehe.
