An idea to make Xbone multitasking better

Xbone can hold 4apps running in the background while playing a game. I was thinking that it would've been cool if you could play some less taxing old school or indie games programmed in the same way as those background apps so that you could be playing some Halo MP and immediately jump into a short burst of something like Geometry Wars. MS should either create lite versions from their existing catalogue of games (but available from one launcher to avoid cluttering of apps) or collaborate with GOG and put some straight ports of 90s classics like Crusader only with native gamepad support; or simply create a cloud based app that is so lightweight it allows streaming of some, most likely older games. What do you think?

They just need to make the interface easier to navigate and not kick me out of gamechat.

The pop up menu from X360 was far superior for most of my multitasking needs.

how short of an attention span do you have that you need to play two games at once?
