Greasy Fork is available in English.
On a post's page, this adds a button to sort all VISIBLE root comments by most liked (then by date)
Additional notes:
This only sorts with visible comments, recommended to pair this script with http://greasyfork.icu/en/scripts/484278-patreon-load-and-show-all-comments/
This only sorts root comments and not the replies.
The secondary sort is implicitly by date. (since that is the original sort)
