ExpStat started as a re-implementation of FuBar_ExperienceFu for DataBroker. I'm evolving it to be a deluge of statistics for XP gathering. All the code is mine, but some of the calculations are the same as in the FuBar_ExperienceFu Addon. New tooltip format has been uploaded. Plans include a pullout window, with graphing data showing time evolution of stuff. Hope to have this working nicely in, and for Cata release.
