Search a bit and you'll find how to install Projectivity/Projectivy Launcher that's way way better. For bonus points and a lot snapper functionality you can go the extra mile and use adb to remove the old Google Launcher and the related bloatware.

If memory serves the launcher/ui is out of their control. It is GoogleTVs launcher and they are forced to use it.

It should be possible to install a alternative launcher that is preferable.

The reality though, is that there's likely bigger fish being chased.
