You may or may not have asked yourself why there's so many API functions dealing with chat windows. No? Well, I have. * Go look at World of Warcraft API#Chat Window Functions. * Then look at World of Warcraft API#Channel Functions. * Now, ask yourself... why are there so many functions doing more or less the same thing? There are functions to join channels. In both places. There are functions to leave channels. In both places. There are functions to manipulate colors there. How many AddOns do you know of that require APIs to change their visual configuration? That's right: none :-)
