I've been pouring through the API all weekend, and I broke a promise to myself and dove headfirst into the tooltips and callbacks. I'll try to remember to post a short blurb on how to catch and hook any event--it's so stunningly easy.
Will also be releasing a tooltip modification library, a la LibAddonMenu, only for tooltips
@Garkin So easy I was able to get rid of dd.Focus and wrap all the prehooks into one function!
