I doubt this will be a native option; it isn't on the iPad and never has been.
I agree it would be nice. Not really worth jailbreaking (for me) for just that one feature though. Makes me have to worry about not upgrading for bug fixes/features. Apple did a great job with iOS7 giving me essentially everything I need/want featurewise to not need to jailbreak. I used to not be able to live without it; even spent about $30 over the years on feature packages. Intelliscreen was a thing of beauty before it basically went native with ioS 6 (I think it was).
