Auxo, my life was made simpler the moment I installed it, isn´t that what Apple is all about ? eheheh
Reason: quick toggles, great UI, easy to close apps (hold to remove all apps from the multitasking tray...), window preview...

But honestly, of course it would be nice to all of these tweaks, either auxo or others mentioned above (which are also awesome) to already be in the OS, however, I´d rather have something different than something that already exists by jailbreaking (idk, apple-made widgets [not similiar to androids, something apple-looking i guess if that makes any sense ahahah), new stock theme (or an option to choose that ´new´ theme) etc.) or they could just improve what they already have, like mail and all that crap they´ll probably improve that in order to not loose usage from other apps that are replacing stock apps... they´ll most likely do this, and ofc improve their baby Siri which i never use, but others might ofc.
My idiology is simple, people who use the iPhone and don´t miss anything on it they use it as default, as it is. Others who have another knowledge on what can be accomplished, go through jailbreaking. And hopefuly, we´ll always have nice people that work hard to get that job done.
But don´t get me wrong, what ever comes is highly appreciated
