Requested feature overview description.
A "Back to Top" button on posts.

Why would it be useful?
When using this site on mobile, it's quite a tedious drag (heh) to scroll back to the top of the page. It would be useful to have that feature for posts with large images, long descriptions, and/or plenty of comments (such as this one ).

What part(s) of the site page(s) are affected?
The Posts section.

Link's a 404, supposed to be post #6268 (yeah it's that one)

Agreed, could be usefull. Maybe also 'down to bottom' for reading latest comments or making your own.
