How about adding full custom gamepad mapping for moga gamepads, It's something I'd like to see because I cant work out how to use the weapons listed as "secondary weapons" in my addon list.

That's something you should be able to handle yourself. I use a moga when I do combat on my phone and didn't have any issues mapping buttons the way I prefer them. Are you familiar with how to set the control configuration options?

The first tab of the control settings allows you to set keyboard/joystick; this tells VO to notice your joystick's analogue input. Next go to the joystick tab; select your device from the drop-down menu (if you have multiple connected, i dont think you do) and configure the joystick axis's (or whatever axis plural is). Finally, go to the keyboard tab. Select a command, then add the digital buttons on your joypad until it is configured to your liking. After that, go shoot some people in sedina b8 for practice getting a feel for your new setup!

Hopefully that helps.
