Thanks is very nice to see how you answer all posts, Im cuban and my english isnt perfect. But speaking of the suggestion, a way to detect that app could be with a button like an ear) to switch to the apps wich are/is using the multimedia audio ouput that is the active app, i dont know, just trying to give ways, im not programmer i will start studing that soon.
Here is another one less crazy, ADD an option to hide system apps or process from the pick list, it usefull to people who hack only games, or add a button in the bottom of the pick list saying SHOW SYSTEM APPS for those people who need it, Other one from this order the proces in the pick list by cpu usage (one of the first ones or the one would be the active game or app)
I give you thees suggestions because you can save the time that you spend looking for your app in the list, trying to make it easier.
