I realize this is a limitation that depends on streaming partners, but since universal search allows for access across channels, thought this is worth suggesting.
If possible, it would tremendous and game changing if I could get a list of recently watched shows on the Roku home screen, as a sidebar option.
Example: Watched three programs previously. Completely forgot what one of them was or which Roku channel it was from.
Goto to home screen sidebar, click recently watched. Click resume on the show title.
