Last December, I mentioned about the release of evasi0n's iOS 7 jailbreak, but I also said I probably wouldn't do it because there's nothing so great when you jailbreak.
Well I've come around since then, because I have discovered the greatest reason for jailbreak: semi-multitasking! My biggest complaint about the iPad is that it only does one thing at a time. That means if you're watching YouTube and you want to check your email, you have to close the application. It's so annoying and disruptive.
With VideoPane ($2), you can have the YouTube float on top of whatever you're doing and have the video running in the background. This even works with podcast or any application that uses the native iOS video playback. It is pretty awesome, you can resize the window and drag-n-drop it anywhere on the screen with, get this, no stutter! Video playback is smooth 100% of the time. I'm running this on a first generation iPad Mini, so your mileage may vary.
What puzzles me is why Apple doesn't allow this to happen on their regular iOS? Seriously, this is a really, really useful thing for the iPad.
