I really would like to see google maps to make use of 3d touch to make zooming easier. Moving the finger up/down while pressing would zoom in/out. That would make one-finger usage of the maps so easy.
You may already know this but you can double-click, hold and slide up/down on google maps to zoom in and out.
I have the 3D thing on my macbook trackpad (force touch) and I have it turned off. Unfortunately the click on the trackpad is triggered by the same mechanism, which means detection of the click is effectively handled by software.
The net result is that, unless you make distinct actions when moving between a zoom and a click, the OS can't tell when the scroll ends and the click begins. I work in CAD software where it's really common to zoom out and roll straight into the click and drag (pan) but it's an absolute nightmare on this trackpad.
The laptop I have right now has a similar pressure sensitive Synaptics ForcePad, and I've never used a more annoying trackpad before. Just simply moving the cursor on the trackpad can be ridiculously error prone, with random clicks triggering whenever you let your guard down and push a little too hard.
The worst part is, I can't even use it as a regular trackpad with tap-to-click only, because the pressure sensitive clicks can't even be completely disabled.
google maps used to have the +/- icons in the corner of a screen.. I found this to be very useful for single hand operation of maps... double tap + sliding doesn't work too well because your slide action is constrained to the range of your finger movement, and typically results in a small amount of zoom.
