Is there any app better than the Multitasking Pro by OryonCorp? I am using the free version. It is quite good and I like the ability to stack Windows on top of each other rather than the Note Pro's split screens. The problem is that in this app, I have to use apps developed by this company. I prefer to be able to use more feature-rich apps that are already installed on my device. Is there an app that allows usage of existing apps installed on the device and allow the users to stack/cascade the windows partly on top of each other?
