I'm just wondering if someone has a userscript that keeps track of the links that one uses when closing questions as duplicate. The main purpose is to avoid having to manually create (and maintain) that list. Instead, have the script update the list automatically every time I close a question as duplicate. Right now, one has to either keep a list of frequent dup-targets bookmarked or just go look for them every time.
The ability to edit the list would be a nice-to-have, but it's not necessary.
