Sorts posts in a 4chan thread by reply count
Adds a "Sort" button to 4chan's navbar at the top.
It lets you sort the 4chan thread by the number of replies to each post, with the most popular or most replied-to post appearing first.
Alternatively you can right-click on the Tampermonkey/Violentmonkey/Greasemonkey icon and select the "Sort Posts by Reply Count" menu option.
