When you turn TV off (I have a Roku-Hisense TV), the next turn on of the TV should return you to the full screen mode of the last watched addon (icon) instead of using the navigation buttons on your remote and then selecting the same icon. Most likely, you have arranged the icons so the most frequent is first on the screen. This improvement would making TV watching easier and more pleasant.
The way it works now, is you are forced to move the selection and verify the choice.
