P: zoom in/zoom out by touchpad on magic keyboard

+1 for this, it's especially felt when you hook up the iPad Pro to an external monitor. If Lightroom is moved to the external display, there's seemingly no way to zoom in on pictures aside from a double click—and I think that seems to be a fixed zoom about of ~100%. 

Pinch to zoom like we have on LR for Mac would be amazing.
