Commons has one of the best that I've seen; it was taken from de.wp, de.wikt and en.wikt - the code for it is at http://commons.wikimedia.org/wiki/MediaWiki:Edittools.js
Something like this was tried on enwiki, but IIRC had the unfortunate side-effect of increasing the load-time for each page to a scary number of whole seconds.
The version at commons certainly seems to have no such problem, and it would be interesting to compare the two: is the difference because of a better implementation or something inherent to the two wikis?
