One of the coolest features of the new Galaxy Note II is the Multi Window feature. Most Galaxy Note II devices didn’t ship with the mod initially, and received updates from their various carriers. Then came a mod that allowed users to add any app they wanted to the Multi Window list, which makes it much more awesome. Now, the mod has been ported to the last variant to hit stores, the Verizon Samsung Galaxy Note II.
XDA Senior Member hairdewx posted a mod that lets users add any app to the Multi Window list. Unlike the most recent mods, which include an app that adds the apps for you, Verizon users are stuck using the old fashioned way for right now. This means de-compiling the apps, making the appropriate changes, re-compiling the app, and re-installing. Once done, the app will show up in the Multi Window bar.
The process isn’t difficult, but it does take some time for those unfamiliar with de-compiling and re-compiling applications. To do it, hairdewx suggests using APK Tool, which is a good idea since it’s well known and tutorials are easy to find. Eventually, a one-click method will show itself like with the other variants.
