Roku needs to develop an app switcher.
My son loves football and I love hockey. There are football games and hockey games on at the same time quite often. In order to switch back and forth I have to go to the home screen, open the app, wait for it to load, then select the game, then select start from live.
If roku could develop an app switcher that will leave an app in the background running and another in the foreground you are watching. It would be nice to switch seeemlessly between the two. Say Thursday night football on Amazon Prime is open and running in the background while I am watching the hockey game, a commercial comes on in the hockey game, I can just switch to Amazon Prime which is still live and running.
