Circuit info should clarify when you are browsing a .onion versus a .com
When I visit gmail.com, the circuit info is displayed as "This browser, relay 1, relay 2, relay 3, Internet." When I visit facebookcorewwwi.onion, the circuit info is displayed in exactly the same way. I realize there are only three hops on "my side" of a .onion connection, but think it would be great if the circuit info box explained that there are some additional hops after that too.
