Not just that, but customizing the filtering tabs -- I get very rare G+ posts from my family, but still that tab lingers there, useless, while I'm forced to constantly peruse the drop-down to the right because oh no you can't add more than one custom circle to your tabs. Seriously, wtf.

You can replace that tab by re-ordering your circles. Those tabs are just the first two circles. Yep, it's not all that obvious.

Thanks, nice one! It's a huge design failure anyway: editing circles has nothing to do with looking at the timeline.
