I also just noticed how the upper part of the home screen, when u select a app in the dock, will show you shows or content relating to the app.
For Channels, it show ON NOW, and i can scroll over as alike to the Quick Guide in the app it slef. This is nice. I can view what is on without even opening the app.
Android TV, on the Shield anyways, has a home screen banner "Channel" that does show a line of icons that is the On now for Channels, but it does not update unless you open the app and open the guide then close out again. That has been a issue since day 1 of me first using channels.
If only there was a Dark / Black and transparent Theme for the TVos version of Channels.
The user that makes the Carbon theme modded app can only do so for Android.
There also is a system level option for sound on Apple TV, Reduce Loud sounds. it seems to be automatic volume leveling. That would be nice to have on the Shield for lat night use, but that seems to be a Apple TVos thing only.
Maybe if the Shield ever gets updated to v10 os, that might be a system feature.
