I'm here to complain about the utterly annoying 'redeem your shit' hovering diff that obscures the main page.
If you are in anyway responsible for doing this to other people, please, take a bit of time and go fuck yourself.
I keep this "Kill sticky" bookmarklet in Favorites for hotkey activation https://github.com/t-mart/kill-sticky and hit it immediately when a page shows a modal, or to delete a fixed header that is making paging with the space bar suck. Worked perfect on this page.
