I bought this for the remote. There's not really anything to "improve" here. It's a dumb box that aggregates streaming apps.
The real differentiator is google assistant (and associated google home ecosystem - if you've bought into that)
What I'm not keen on is a cheap box that doesn't have enough RAM, so that it'll end up lagging. I don't understand why there isn't a premium model. I also don't want to dangle a weight from my HDMI port. That's probably how the HDMI ports broke on my last TV. I also would like to have volume buttons on the remotes. A mute button is nice but not enough. I'd rather trade the youtube and netflix buttons for real volume control buttons.
It looks like the remote has volume buttons on the right side by the way.

That’s good news on the remote though
Google's take on the TV app from Apple that runs on Apple TV, iOS, and Mac, serving as a common UI to content from apps that buy into the partner ecosystem.
Awkward how unclear that site is: this new app from Google is to be the UI pre-installed on future Android TVs, but for now, you can get as a thing running on a $49 Chromecast puck.
