Thanks Parp. I will be making regular updates to it as long as new ideas come up. Don't forget OS X too
Although that is a separate purchase.
I am going to add shortcuts to the "top shelf". If an app is one of your first 5 then it can show some extra options at the top of the screen before you launch it. I am thinking of adding the option to have your favourite presets there.
Another cool feature that already works is the ability to use the Siri Remote -
when in the app - to control it, it will even work with any custom voice commands you set in the iOS version of Home Remote.
You can leave it with the app open, and sleep off on the Apple TV and even if the TV is off or you're not on the right input you can still use the Siri Remote.
