This addon will be mostly useless for most people, I created and uploaded it for personal use. If you're curious why I am doing this instead of just pressing the "filter by hash" button is because I made a script that given a hash and some parameters generates all the filters I want (not just hiding but also different highlights, who does it apply to, etc), making sure that there is no clash between filters (eg a filter that hides it and a filter that brings it on top) I honestly can't think of any other reason why you'd want to use this addon.
