Looks great! Ever plan to release the addon?* UPDATE *
So my little add-on has morphed into something much more complex than I ever thought, this latest update now allows each game tile to be clicked to show game info including the list of achievements for each game.
It took a lot of work as getting the data for each game isn't easy but I got there in the end. Phew!!
