Also the cpluscplus example. It throws structured data in a completely unreadable format and ads paddings to the navigation where they are surely not needed.
Shouldn't this be called "Bootstrap Me"? The beautifying is simply just inserting bootstap.css into the current tab. Cool idea, don't think it needs jQuery though and popup.css can be stripped down massively.
The increased padding on the Chromium site is great, but to me the HN 'after' looks quite a bit uglier than the 'before'.
