I've been working on mine (MoBuffs) for a while now, since TBC came out. I decided to release it recently after switching it to use Peragor's talent lib.
I had a try of your addon. It won't work giving me an error about a callbackhandler. Try it with no addons installed and I get the error. Sorry can't cut and paste. Error comes up on start up when in a party.
Looking at the wiki page and info it looks very good - with exactly the same ideas I had! Amazing. Just mine was released a week or 2 earlier. I like the even more comprehensive reporting you have but not the layout of the reporting and lack of dashboard and I assume to raid too (can't test as it does not work).
You appear to check for temporary weapon buffs by looking in the player's bags? I was assuming I would do this by a different method. Perhaps this post should be in a topic for your addon.
