Hide torrent rows based on checkbox state
This script will hide torrent rows matching specific criteria set with the checkboxes in the filter box. It also adds a toggle link in the linkbox on top, to show/hide the hidden torrents as well as the total number of hidden torrents.
Only thing to configure is the placement, which is done by changing the FILTER_BOX_POSITION constant to either 2 or 3 (or 1 if you hate album covers). This helps you adjust the formatting of your torrent page in case you have any other scripts running with link or settings boxes.
