Nope.
I agree it's difficult to understand why Apple an overhaul of the app switcher was needed. But I got used to it quite quickly, TBH.
well, it's designed to make sense alongside the new 3D touch "swipe in from the left side" on the iPhone 6S"
double tap the home key and imagine having just "force swiped" in from the left edge of the screen. The animation / the design does make sense.
i don't mind my contacts not being there anymore. That feature felt awkwardly redundant.
Yeah, and it scrolls from left to right instead of right to left.
ever since phone's got bigger, i do believe the main "phone hand" has become the left hand, as you'll often need your right hand as a "stylus" - especially on the 6+ / 6S+
the app "carousel" makes sense to me, i think it's much easier to force quit apps with one hand now.
also, "new" apps come in from the right (like, when you open the app store from within a safari link).
Left, in general, is the "back" / "previous" direction. I think the way it was handled before was actually off.
Oh, also, i've started using "Ghostery" instead of adblock on desktop safari right now. It's a very clean experience and blocking / whitelisting individual features / trackers on a site-by-site basis is really nifty. Like only having social share buttons on sites you actually share articles from, etc.
