Greasy Fork

Useful script, but it seems to conflict with another userscript and prevents it from running. This is the script in question: http://greasyfork.icu/en/scripts/460680-youtube-tools-all-in-one-local-download-mp3-mp4-higt-quality-return-dislikes-and-more

I checked that it have many layout changing code. Better to ask its author to fix the conflict

I've sent a message to them too. Thanks anyway.
