There is another way. GMail allows to use compact interface. There is option to turn it on: click on 'gears' icon in top right on the top of table/list with e-mails and switch onto compact view. You can also turn off those "Primary", "Promotions", etc. labels.

Those are options but definitely don’t come anywhere near what the author has achieved! I’m actually very impressed with the new interface.

I can’t believe it, but I’m actually at the point where I no longer enjoy using Gmail. I have an easier time using the Windows Mail application at this point... which is really telling I think.

Yes, this. With no external (CSS) tweaks my Gmail interface looks just fine, tight and compact:
