== ReferenceTooltips == 

 Great work on improving ReferenceTooltips. It seems really solid now. I made a small code tweak to reduce the footprint a little and insure future compatibility with our jQuery UI skin: http://en.wikipedia.org/w/index.php?title=User%3AYair_rand%2FReferenceTooltips.js&diff;=500739549&oldid;=500406057 

 (The button() function is what normally adds all of those css classes and the internal span, so there's no need to do it manually.) 

 I'm not sure what's going on with Cite.php currently, but I'd still love to see this turned on by default (especially now that it has a configuration interface).
