This is just a suggestion. Couldn't find any other place to post.
It would be nice if ROKU would include a "previous channel" button on their remotes, like on other remotes (DirecTV for example) when you are viewing TV via a streaming source such as You Tube TV, FUBO, Hulu, etc.
Kind of a drag to be watching one channel and want to watch another one, scroll to it and when watching that channel want to go back to the original one you were watching but have to scroll through all the channels to get to it. If there was a "previous channel" button, you could eliminate a lot of scrolling.
Each channel/app could implement that functionality itself. It could use something like the * button on the remote. I'm not sure having a "previous channel" button on the Roku remote would make sense. In the Roku vernacular, a "channel" is an app. Some people might like a button on the remote that switched back and forth from Netflix to Youtube or whatever, but that would just be one more button I'd have to rip out of the remote like those stupid partner buttons.
