So I don't know if this was a feature on the 6S or it came with iOS 10, but the System Haptics on my 7 Plus are pretty cool. This is especially true for spinners where it clicks the haptic engine as fast as you can spin the selector. Other things like sliders have a center click and pinch to zoom, etc. It's actually usable feedback in situations like when you are on a moving vehicle (tram, shuttle bus, for example) and that click gives you the snap-to setting you want. Anyone else find this useful?
