Is there a point to the cards Multitasking UI in iOS 7 ?
The new UI does not give any real functionality ,infact it makes switching more tedious since it just shows about 3 apps in the view that you can switch over to. You need to scroll more compared to the older one ,the older one was MUCH more simple and elegant and did what it was supposed too. And really ,why do you need an 'App Preview' ? It's not like you can browse your facebook/twitter feed from just the app preview and you can't play Music or type an Email from just the App preview. The older multitasking bar showed more icons and was easier to switch and probably used much less resources then this cards style solution. Plus the old UI made so much intuitive gesture sense ,i.e swipe up from the bottom to reveal the tray ( eg jailbreak tweak Zephyr).
