I was initially intrigued by having buttons on the bottom of the controller, where your fingers naturally would be thus freeing your thumbs to stay on the pad/sticks. And imagine my frustration to realize those rear buttons are just extensions of triggers already on top.
My set up approach to having both my thumbs stay on the pads a majority of the time has been to set up a dpad modeshift with an inverted outer ring bind so clicking up, down, left, right, center output different inputs. And depending on the game I’d set up a chord so holding the left grip and clicking the right pad would output a different set of 5 inputs. And my right grip is set to jump so with the left grip chord function for 5 additional inputs on a right pad click if needed for a total of 10 that’s been my way of doing that.
So for like Doom Eternal I swap between weapons every shot to bypass reloading through the right touchpad. I like that approach better than using stuff like weapon wheels, which in some games actually slows down the actual gameplay and interrupts the flow.
Prey was great in that department actually having a config that mapped mouse to the right touchpad instead of emulating a joystick like so many games did, and then had different action sets that automatically switched depending on if it was gameplay or you were in the menu. And showed proper icons like the touchpad click to reflect Steam Input mappings people set it to.
