This is a simple LibDataBroker plug-in inspired by Fubar_switcherFu. Clicking on the icon will switch the display between full-screen and windowed mode. Right-clicking on the icon will take a screenshot (stored in the WoW Screenshots folder).
Like all LibDataBroker plug-ins, Broker Switcher requires a data display addon like ChocolateBar or DockingStation.
Changes in version 1.2: the current mode is shown in the tooltip (thanks to GreyWolfSC) and the tooltip is hidden when a screenshot is taken.
Added shift-left-click option to select Windowed (Full Screen) mode.
Added option to display a grid for helping set up display objects, cycle between green or red lines.
