Google Reader's lack of overview

I spent half-an-hour to see if I can migrate to Google Reader after reading about their cool new sharing feature. That did not exactly work out unfortunately. It's fast and pretty looking, no question about that, but the thing it's missing is a high level overview of some sort -- something that would say "there are 4 new posts in that blog", two in this and one in that. Some blogs I want to read right away, some may safely wait till a coffee break and some I may just "mark as read" at the end of day if I did not get around to reading them. Reading an unprioritized blogroll is too much for me.

Back to trusty Thunderbird.
