So, without using Atomic scripting i can not do exactly what you want. Unfortunaly i don't have time to make a scripted layout right now.
Without scripting , just with the layout editor , i managed to do this :

You can not click directly on the picture.
You can browse game using arrows left and right. And you can jump to next or previous page using double Arrows.
In Atomic 0.19 , You not switch to favorite list by touching the screen, you have to press a button. But if you are interrested in that kind of layout, i could easly add this feature in the coming version.
It is not exactly what you want.
You can also make variant of this layout, by using text list and one snap or any various combination. For instance , you could have a text list on the left , with at the top and bottom of the list , 2 "touch" zone to browse the list. And on the right A Snap (or video snap) , and you could touch the snap to run the game.
But as it stand now, You can not select a game by touching the list.
Let me know, if you want try it and if yes , send me your email in pm!
