Noticed this in SVN, converted from the old FuBar_Tracker. There are some errors tho, for example the default trackframe keeps popping up when events are fired, and the texture for the icon is not changing properly. Seems that I was able to fix these, but since I'm not really a coder maybe someone who knows the code a bit better could check out the .patch and implement the needed fixes to SVN. Sorry if this is not the right place for this.
The Thaddius ChargeEvent isn't working. As far as I can see, the event CHAT_MSG_SPELL_PERIODIC_SELF_DAMAGE is not fired at all. One alternate way to check the polarity would be to check buff icon textures after the charge fires.
