And if there's isn't an addon that can do what they're asking, maybe this comments section will be the impetus for someone out there to create one of their own. Think we can find a need out there for an addon that doesn't yet exist? Of course, there are some things that addons can't do (choose targets or spells for you is a big one), but otherwise, consider this thread your clearinghouse for addon service requests.
If you can't get an answer here, feel free to tip us, too -- we at WoW Insider always love finding out and writing about new addons. Whether you need help finding an addon that does what you want or you know of a great addon that could use some coverage, let us know and we'll be thrilled to take a look at it.
