this might be an opportunity for addon makers here to take over the code base from zygor this thread suggests a way in the last post but i doubt zygor would go for it
they are dropping out of providing guides for anything but WoW it seems
Yeah, it wasn't released for free which I always thought was just the worst thing ever. That being said, I "saw" the addon in use once cough and it wasn't terribly interesting or useful.
And on top of that, there are so many leveling guides on the internet I really don't see the usefulness of having an ingame window telling you what you can easily read for free somewhere else.
I researched a few interference issues with MiniMap a while back and had my hands on this add-on for testing purposes, while it looked appealing and user friendly it had massive impact on game performance.
