The 3D Touch on the keyboard to edit text is absolutely amazing. I use it all the time and saves me a lot of time. I love it. It's a shame that most people don't know about it. However I don't use any other feature with 3D touch, either because I don't know about it or I find it useful.

That feature is also available without 3D Touch, just use a long press.

The long press doesn't have the same capability. With 3D touch you can also select text by pressing harder on the screen, which is the real magic of that feature.

I also use 3D touch along the left edge for app switching.
