Buried deep within the first beta release of iOS 7 are a handful of neat and potentially useful features. The hidden enhancements were dug up by Hamza Sood and offer a tad bit of insight into what we might expect in later versions of iOS or even when the latest version ships to the public this fall.
How to actually access the hidden settings is unclear as it doesn't appear to be readily available to everyone with the beta. The above video shows a handful of nice-to-have tweaks like the ability to nest folders within folders now that iOS 7 has pages within folders. You can even hide pre-installed apps!
Other hidden gems include gestures that are activated from corners or swipes from the edge. The latter of which can already be found in Mail and Safari, for instance. As 9to5Mac points out, we could see these new-to-iOS gestures for quicker app switching later on but not much else, as the settings are hidden and likely only for internal use.
