3D Touch is missing the most obvious thing to be mainstream. Visual cues.

This. So much this. There is nothing in the interface that signals to a user that a particular element will respond to force/3D touch. The only way to tell is by trial and error. And then, once you’ve figured it out, you have to remember what works, or trail and error all over again.

And what’s great about this writeup is that Eliz not only identified the problem, but came up with an elegant solution. Check the last three images in the article, see if you can tell which controls are force touchable?

Eliz tied this up with a bow, handed it to Apple. Here’s hoping someone is listening.
