I suggested this feature via email but i think it'll be nice to have for the older cameras that do not allow multiple points selection.
The feature is already in ML but you have to have particular settings to make it works and not everybody uses them.
It would be convenient to have the patterns as bmp on the card so you can see what you're selecting in the relative menu.
AF points pattern are already done (i saw them on the wikia) and it'll need to pair the visual hint to the actual selection.
