I love Dugi's Guides. I have them all and keep 100% up to date.
I have Zygor as well. Dugi wins: simple UI, Minimal eye candy, better guides all around (IMO).
BUT, there are some worms in the pudding.
I would like to report them in the course of using the guide. However, I'm extremely lazy and want the comp to do the drudge work of collecting all the pertinent data. Then I can fill in the rest of it.
One button to gen up the data and a in-game form from which I can 'copy to clipboard'.
