You will need to install a user script manager extension to install this script.
What this script actually does:
* Automatically expands the 'And x file(s) more' links
* Adds a button to torrent pages that allows you to expand or minimize all the folders at once (picture below)
1a. Firefox users: Download Greasemonkey
1b. Chrome users: Download Tampermonkey
2. Click the green install button on the left-hand side of the screen.
Follow the on-screen prompt, and click 'Install' / 'Ok' on the pop-up window then you're good to go.
* None (if you see any, let me know!)
P.S If you use a mirror rather than the normal kat.cr site, you'll need to edit the script; change the 'match' / 'exclude' statements to the domain you're using (you can add multiple if you like).
