Can anyone explain why when I used the wau for first time it added a whole lot of libraries I didn't select? My addon folder is a mess now and when I start wow and look at my addons there is probably like 50+ new things trying to load now. I really dont want all this crap running and slowing down my computer if its not needed. Is there a way to fix this or do i need to delete the whole folder and start over? Thanks for any help.
You've updated using "without externals", which means "don't put the required libraries in this addon's folder". You also used "automatic dependencies", which automatically downloads the libraries each addon depends on. Since you're using "without externals", this places those libraries OUTSIDE of the addon's folder.
This does _not_ slow down your computer because it would all be running/loaded anyway (but be contained inside the addon's folder instead of the main addon folder). The only downside is you have a bunch of non-addon folders in your addon folder. The upside is that WoW will only load those libraries exactly once instead of once per each addon which uses them, significantly speeding up the process of entering the game.
It's down to a matter of preference, really. I prefer not waiting four minutes for WoW to load, myself :)
