Userscripts for staff usage
A while back I added a userscript that will tell you whether or not a series page contains dead links (i.e. titled slots that don't currently hold an actual article). It adds a block at the top of the page telling you which titles need to be removed.
In addition, I've just uploaded a userscript that will tell you the real rating of a page. This is useful information for anyone, but particularly useful on pages up for deletion, to check its real rating when double votes and votes from deleted accounts have been stripped.
Have fun. :)
