Nice!

@Alex11110
please use the new one at https://gist.github.com/griffi-gh/2cf11b9763b5158337d649d3b64ae154 instead.
this one's broken and there's no way to unpublish it without deleting.
(new one may broken too but idk, i havent touched it for a while; can be used as both userscript and bookmarklet if minimized and wrapped in a function call)
