Federico Viticci lays out his favorite new iOS 12 shiny. All worth reading, but my favorite:

Previously available only on 3D Touch-enabled iPhones or with a two-finger swipe on the iPad’s keyboard, trackpad mode can be activated in a much easier way in iOS 12: just tap & hold on the space bar until the keyboard becomes a trackpad. This mode (seemingly inspired by Gboard and other custom keyboards with a similar implementation) gives owners of iPhones without 3D Touch a way to more precisely control the cursor in text fields.

This is one of my favorite new features and, to me, feels much more responsive, the cursor much easier to control.
