Go here if you want to vote for some new features. There is also an "Any other ideas?" section which is open-ended at the very end. I requested a pop-out sidebar where you can access user profiles, gmail inbox, and many other things. I also requested to have full Google Calendar integration so from that sidebar you can access your calendar without having to open your web browser.
If you like any of my suggestions then request them too and they could become a possibility. In addition, make sure to request some other features that you can think of.
P.S. thank you SGT for posting the link.
