iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Hidden iOS 7 Settings Reveal Potential Gesture and Folder Enhancements

The gesture settings include options for a new "corner swipe" gesture. In addition, there appear to be expanded options for the "press and hold" gesture, which has so far only been used to prompt "edit mode", which allows users to move and delete apps. There also appears to be a section for "edge swipe", which has become prominent in Apple's redesigned stock iOS 7 apps. 9to5Mac notes that the settings indicate that these gestures could be used for quick app switching.
Other settings include additional functionality on the home screen, such as being able to completely delete stock apps like Newsstand, which has long been a requested feature from some users. The ability to create folders within folders is also present.
The final group of settings is used to tweak the visual flow of the new operating system, with settings responsible for blur effects, coloring and animation speed.
As 9to5Mac notes, it is highly unlikely that most of these features will make their way into the final public version of iOS 7. Instead, the hidden settings are likely to be used and tested by Apple internally to not only tweak iOS performance but explore future features. Some could, however, be adopted as public options to allow for further customization of the user experience.
