Feature Request: Key bindings for thumbs up/down in G-Play

I'm not sure if this is the right place to post a feature request, but it'd be really great if there were key bindings for different player functions. What would interest me specifically are the Thumbs Up / Thumbs Down buttons for Google Play. Would it be possible to implement that? Of course, the coolest thing would be for the key bindings to be customizable, like in Amarok. And while I'm at it, the next great thing would be to have key bindings for showing/hiding the main window and showing the current song.
