Userscript for web browsers. Runs on gumtree.pl and adds an eye icon next to each entry in the listing. When you click the eye, the offer gets dimmed (15% opacity), and its description is saved to local storage, so that duplicate offers on subsequent pages are dimmed as well.
Made to eliminate duplicate offers, which may appear quite a lot when searching for a house. To bump their offers to the top, brokers tend to re-issue them, without deleting the previous entries. Tree Saw lets you hide these, as long as the description matches.
