• But it (B) should not sa ChaHub, it should say “Codalab”, “waggle” or “RAMP”, whatever the platform is. We need to show specific stats and say to which provider this corresponds to avoid any confusion. If this is for all of Chahub, we should also say so.
• While expanded, the "shrink" button follows the screen, it shouldn't follow us as we're scrolling down, unless it's already shrunken and needs to be expanded

• On spinning up PR server it should show some dummy stats for General stats instead of 0's
