Personally I use the SST software; I have a lot of things mapped. I use the clutch button as a second shiftstate, like the pinkie button, so that I have 3 modes; each with 2 shiftstates...for a total of 9 options for (almost) every button. For example; my C button is mapped to Trim (press button), Cancel Trim (hold pinkie trigger and press button), and Emergency AutoPilot Off (hold clutch and button). I have the the Fire key mapped to Uncage Shkval (press fire button), Laze Target (pinkie and fire button), and Reset Targeting (clutch button and fire button). So far I've only got Mode 1 (Nav) and Mode 2 (Attack) programmed; but soon I will try to finish mapping Mode 3 to be a cannon mode, or maybe a weapons control panel switchology type of mode.
I do not use the slider for zoom view, I use the up and down on Hat2.
