What steps will reproduce the problem?
Everything is working as intended, however everywhere - wowace, curse, WoWI, the options - state that there is the ability to filter error messages, but I can't find it and many others cannot find it either.  Was it removed?  Do I have to stand on one leg and quack like a duck before they appear?  Thanks for your hard work, other than the errors not being able to be filtered its a great addon.

What is the expected output? What do you see instead?

What version of the product are you using?
r85

Do you have an error log of what happened?
No error
