Basically, this takes the annoying graph search bar and fixes it: it takes up less space on the top of the screen, moves the notifications back to the left side of the page (where they belong), and nudges upward the drop-down thing on profile pages. Pretty self-explanatory.

The post request is interesting too: http://i.imgur.com/mE8CVyp.png

I think it is strange that you tried using the developer console rather than using TamperMonkey, which is the userscript system for which this is written o.O
I worked perfectly well until just today--I guess Facebook changed their styling again. I'll figure out a fix and update this gist.
