We have Roku installed in a bedroom used by my elderly mother so we try to keep the TV interface as simple as possible. It is primarily used to access the Xfinity (Comcast) app. Since it takes forever to boot up we leave the Roku on all the time. The Roku remote has a button to turn off the TV but if you do not hit the Roku 'Home' key first Xfinity will just keep streaming for up to 4 hours after the TV is shut off. Needless to say she does not hit the 'Home' button all the time.
A useful feature would be to have the Roku return 'Home' when the Power button is pressed, in addition to shutting of the TV. It seems like this could be an option in the 'Settings'.
