Display controller layout withing Launchbox/Bigbox

[Jeck11]

Please create a way to display a controller layout for each platform. I'm envisioning something like an image that I've created being called from a right-click menu or something.

I'd also like that!

This is currently possible both at launch of a game and during pause. LB had added Startup Themes and Pause Themes which can display custom images such as controller mapping.
