Looking for an Android Launcher that will dedicate my Shield to CDVR

I know there are a lot out in the play store. I have tried a couple and so far they aren't easy to setup nor allow me to dedicate that shield to one app and auto launch it each time the shield comes on. Of course it needs to have an easy to see way to stop it from autoloading when needed. If anyone has found a good one that works on shield devices (and or Chromecast) please let me know what one it is. -Bill
