Maximizer is technically a 3rd party program (anything other than wow.exe is).

But it has so many practical uses and all it really does is display the window differently. Similar to other programs thas have been used on other mmorpgs for years.

Not only has it been around nearly 2 years, it has also been partially integrated in the official client.

I don't worry about maximizer at all. AHK I do worry about a little bit.
