I've only been using Channels for a couple of weeks, but one thing that I find could be improved upon is that it's hard to tell which tile is currently selected when browsing TV Shows, On Now, Up Next, etc.
While you are actively moving the focus around it's pretty easy to tell, but when I first bring it up I have a hard time telling which tile is selected. I am mainly trying to make the interface more wife-friendly.
Would it be possible to add an outline or glow to the currently selected tile?
