Bigscreen launcher should open the existing application if it's already open instead opening new instance every time

As title. In my opinion Bigscreen launcher should not open multiple instances by default, instead it should reopen the existing application if it’s already open. A TV UI is a pretty singularly focused experience (meaning you do a single thing at a time) and Bigscreen should reflect that.

Maybe I’m mistaken and it doesn’t do that, but that’s my experience.
