If I could just set my "Friends" circle to be the default function of the Home button (something I've wanted dating back to my first 5 minutes using the service) I would probably actually use Google+.

"Home" being "EVERYTHING" is just a disaster. I want to see what the people I actually personally care about are up to first and foremost, and then I want to browse around to what the rest of the Internet is doing. Instead, everything is shoved down my throat all the time.

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.

They fixed this somewhat recently. For every circle you can control how much content will appear in the Home timeline.
