Add Unlimited Apps to the Galaxy Note 2 Multi-Window Selection
Some time ago, XDA members put in the effort and figured out the applications that are compatible with the new multi-window feature found on the Samsung Galaxy Note 2. It turns out that list may not be necessary anymore, as a mod was recently released that makes any app compatible.
XDA Senior Member goddamnit has released a mod that allows users to add any application to the multi user interface. It also allows users to add as many apps as they want. This is one of those mods that everyone knew was coming, but that doesn’t make it any less awesome than it’s actually here.
Using it is pretty simple. You flash the mod in recovery and then you should be able to add whatever apps you want to the multi window. Of course, this is an early release, so there are some bugs. First and foremost, you’ll have to flash the mod made specifically for your ROM’s version. Currently, LJ1, LJ3, and LJ7 are supported. There could also be some problems depending on whether your ROM is odexed or deodexed. As per the norm, your mileage may vary.
