How to Add Apps To Galaxy Note II Multi Window Feature
The Galaxy Note II has been praised for many of its features, notably its multi window feature. The only issues some users are being faced with is the amount of supported apps, which is pretty much limited to pre-loaded apps, primarily the Samsung ones. Thanks to the devs at MoDaCo this can quickly become a thing of the past without waiting for 3rd party devs to include the multi window ability into their apps.
As you can see from the picture above, I have Google+ and Go SMS Pro both using the Multi Window Feature, and both of these apps are currently unsupported.
Doing this method Requires Root Access and of couse is one of those Try At Your Own Risk situations. I highly recommend making a backup before trying this, I personally had no issues.
I can confirm this works on the international N7100 model, but North American Carrier branded models are an unknown at this point.
