Officially introducing the only permitted 3rd party program, FFXISwitchMon.
This program is designed to give you alt-tab functionality to the controller, preventing you from needing to go to your keyboard to switch between windows. It relies on .net framework 2.0, and must be run as administrator to function.

As always, the use of any add-on's, plugins, or 3rd party programs that are not officially supported by me is strictly prohibited.
