I think it would be cool to have Retroarchievements integrated into AM layouts.
For example in one of the corners (depending on the layout) to show which username u are logged in as + profile picture + total number of points.
And the more difficult one to have information from Retroarchievements per game ... for example show general info about completion like "xx%" and "Earned x of x achievements, x/xx points." and the ultimate it will be to show the actual archievements (those little images with name) on button press.
just thinking out loud
