How would you change the Roku 3?

When we're recommending media streamers, our first thought is always toward the Roku 3. After all, it's got the best features of the Roku 1 and 2, a motion gaming remote and, slightly belatedly, now even supports YouTube. Our question, if you choose to accept it, is what you'd want Roku to add for a (theoretical) Roku 4? For our part, we'd love to see native live TV support, so we wouldn't have to switch between that and the Chromecast during the World Cup. Got a better idea? Come to the forum and share it.
