Realized that there's somehow still no decent jailbreak tweak that brings real multitasking to the iPad, so I started on this concept;
Runs two portrait apps in landscape mode (or two landscape apps in portrait, but this works/looks better), with a little carousel app slider at the bottom of each showing all the apps from the switcher. Still incomplete, but you get the general idea. Activation method would use the current four finger gestures to switch between apps, except stopping in the middle and releasing to join the two.
I'd love to do something as simple as browse gaf while watching a YT video, or writing while studying/reading from safari, etc. Pretty much the main advantage my MBP has over my iPad tbh.
Ah well, might post this one on the verge and hope someone turns it into a JB tweak as well. :lol
