I've been working hard on a couple of other projects (KeybindTrainer, KeybindViewer, and the KeybindTrainer Website). I've noticed this site is in dire need of a data refresh and a few other upgrades.
My next set of "todos":
- Update all spell/item data so the hover tooltips function again.
- Update the macro grammar to reflect changes up through 4.0.6
- A few small bugfixes I've seen in the logs.
Thanks for the comments, and glad this tool has been useful to so many people!
