< Feedback on [Deprecated] AutoSortXReplies
Twitter has changed its sorting in the most dumbest way possible, wait for a fix.
Update: this script is deprecated, it is a pain to work with twitter dom and due to the tampermonkey limitation I am no longer maintaining this userscript version, however, you can check out the add-on version on GitHub instead. https://github.com/RoyRiv3r/AutoSortXReplies
No longer works
