According to https://www.w3schools.com/js/js_cookies.asp , you set the cookie's expire date to sometime in the past. AKA you force it to delete itself.
added a button to clear all settings. also settings are saved in LocalStorage rather than using cookies now, you might need to re-select your settings
Added a few links to the UFSC, fixed a CSS error i didn't catch until now
Also just pushed a fix for the display settings not working right on the art gallery pages
