UX 4.0 Questions [May Apply To 3.0 Also]

[bigbluebanana]

1) Is there a way to replace smart notice with a Google Now alternative?
2) I love smart bulletin a good bit, but can you get widgets for an individual bulletin? I want to throw a QRemote widget into my "Entertainment" Page
3) I love my Nexus Player, but we also love our Roku. Does the QRemote have that sort of control? (We have a Roku 2 XD)
