Watch Later - A Few Things
This isn't limited to the Roku implementation (these thoughts apply to the Xbox One app, too) but Watch Later needs a little bit of love. Two things:
First— it takes A LOT of clicks to get to it. I just checked and it took me 13 clicks. Maybe there could be a setting to enable it so it appears under the library area. Or, maybe a UI tweak that allows you to select "On Deck", "Recently Added Television", "Recently Added Movies" headers, by tapping up on the remote could help. It's also easy to not even know it is there. People are used to scrolling up and down in browser windows, and in apps. But, it is less common to scroll left and right, especially that far right.
Second — On Roku and Xbox One, it just leaves watched items in the list. In older clients, like PHT and iOS it would remove watched items, which makes a lot more sense.
Love the new Roku release. This is a really solid release, I was very excited to test it out. Congratulations, looking forward to seeing some of this stuff trickle into my other room and onto my Xbox One.
