A new tweak allows us to run several applications in the same screen

I've been thinking for a very long time if such a tweak could ever be developed and here it is Aaron Nash proves to us that anything is possible on the iOS platform. In the image above, we have demonstrated the fact that 2 applications can run side by side on the same screen on an iPad tablet. Aaron Nash managed to develop a tweak that allows us to run 2/3/4 applications in the same screen of our terminal, all functional but up to a certain point. He managed to successfully run 3 applications at the same time in the same screen, he played 3 versions of Angry Birds at the same time but when he got to the 4th application the tweak closed everything due to an error.

Yes, and it actually works! I've wasted plenty of time already playing 2 games of Angry Birds at the same time. (I actually was playing 3 for a while, but it crashed when I tried to add a 4th). There are a few bugs, such as audio not working, and accelerometer events not getting sent to applications; it may take a while to sort these out. The bottom right button turns on "edit mode" which allows you to rearrange applications, and rotate them (Angry Birds normally runs in landscape, here they're turned).

The tweak is specially designed to allow rearranging the windows of open applications and from what I can see, the developer uses the way to view iPhone applications in this tweak. Unfortunately, the tweak does not recognize the accelerometer and the applications do not have sound, but the idea is excellent and if he managed to present it, then surely someone will be found to complete the concept. What do you think, would such a tweak be useful to you?
