This script adds a gear in the bottom right corner. Clicking it will open a GUI. Here you can set filters for videos you don't want. Videos that match the filter will be removed from your youtube home screen, subscriptions screen and the bar on the right side.
Currently, you can filter by exact channel names or partial titles. For example, you can write your title filters like "porn, 100 degree, prank" and videos like "1000 degree knife vs cake" and "epic pranks GONE SEXUAL" will be hidden.Known issues
