A few weeks ago I wrote about some productivity tricks in OS X, and now my twitter friend Ivan Nemytchenko made a one-week course about his OS X productivity tricks.

It starts on February 8th. After subscribing you'll get an article "How to stop suffering from too many tabs in Chrome".

Here it is http://productivitymode.com. I think it should be good. And it's free, there are no reasons you shouldn't subscribe.
