Have you ever found yourself wanting to merge references, and then found it tedious to find and replace all the reuses of that reference? What you need may just be a script called RefMan (for Reference Manager), which allows you to drag and drop references into each other to merge them. You may also update and delete references. It is similar to ProveIt, however, there are some important differences:
<ref>
tags, and parses ((cite))
templates and such. RefMan makes no attempt to understand, apart from finding the URLs.<ref>
tags. It will find them both, but if you try to edit the second one, it will change the first one. RefMan works very differently in that regard, it makes no such guesses. RefMan is like an all-seeing eye. If you get my drift.<ref>
tag, RefMan highlights which reference that is in RefMan's interface, making it easy to switch between editing the wikitext and using the RefMan interface.((subst:iusc|User:Uglemat/RefMan.js))
