These are the addons I use or recommend. Any addon marked with an asterisk I have recently stopped using (or replaced with a weakaura),
but will keep in this list for reference. Most of these addons are from Curse, and I use the Curse client to keep them updated.
A couple of them however are from WoWInterface.com.
Some of these addons may also have become broken since 7.0.
Any addons with an asterisk in the title are ones I have stopped using, but others might find useful.
