A handy feature that should be added to the Roku remote control is a "Jump" option. By that I mean pressing a button to return directly to a previously watched station without have to scroll back to find it. This option is available with many other remotes.
ALSO.... get rid of the "because you watched" suggestion feature!!!! It's annoying and should be a user-controlled option. It's really annoying when providers feel the need to offer viewing suggestions.
