Although the thumbsticks are now working, and showing up in the Controller Config screen, neither of them are yet configurable.

I'm not really sure how best to make them editable, as the menu currently has a certain amount of logic to it.

Up and down to select a line of buttons.
Left and right to pick a button.
Primary button to reconfigure button.

Whereas the two thumbsticks are oddly out of the way, and don't "do" configuring.

I need to rethink how they're done, I reckon. Simplify, and make it more obvious.
Hmmm...
