1. swapping the sticks:
so that the right stick would act as the D-pad and the left stick controls the cursor
2. changing the controller cursor sensitivity
i personally find it slow as heck
3. remapping default actions
when using the cursor, it's uncomfortable to shift my right thumb between the right stick and the cross (A) button, so I'd much rather remap it to something like R2 (RT)
4. changing the button glyphs
like to playstation or nintendo styles
