While the feature is quite useful as it comes, our developer community isn’t exactly known for being content with stock features. As proof, we have seenseveralmods that extent the feature to support almost any app. XDA Recognized Developer LegendK95 has taken it one step further and released MultiWindow Complete Control for the Verizon Galaxy Note 2.
As the name implies, this mod grants you full control over the MultiWindow bar, allowing you to easily add or remove applications, sort them in alphabetical order, and even control Samsung’s predefined applications in the MultiWindow view. Do note that the mod is available for devices running a deodexed ROM based on the VRALJB firmware.
You can find more information, the download link, and installation instructions in the forum thread.
