I don’t really see the benefit here. Ok so the app doesn’t fill the entire screen but it still uses so much that any other app that is open behind the app in the forefront can’t be seen or used. I am not seeing how this is any different from standard multitasking in Android.

  It’s just the foundation. Perhaps they will implement the idea that samsung has used where the windows are resizable and movable

    If they allow for seeing two apps at once, that will be an improvement for sure. Granted I still do find the Android multitasking to be rather sufficient.

i don’t even know what is that. their pie interface is rather useless, making it more difficult to navigate the menus

I simply don’t get it! This seems to me to simply be multitasking. I settled on the JBSourcery ROM (after trying about 7, including PA), and found it to be one of the best for battery, CPU utilization, speed and general functionality (especially camera) – the “really important” stuff.

If they could give me a way to show a useful split screen (current ones are all quite useless) or a floating Note app, something along those lines, then I’d say they’ve done something useful. Showing us 90% uselessness equals 0% usefulness.

C,mon people this is not useless ..its basically chat heads on every single app ..look on g+ at paranoidandroid. There is a better explanation to it ..anyway well done PA TEAM .
