Like firetv does roku have a watchlist? (Where i can put all my fav shows each from a different app in a list together). I just bought roku express and i cannot see it anywhere
No, Roku does not offer that functionality. Some individual channels might have that in the channels themselves.
Roku does have something called My Feed, but I don't think it does what you're looking for. You can tag something to "follow", but I have no idea what that does.
