Sometimes you trip up over something that’s been there for ages: Today was one of them.
I found if I did something in the Version 2, something cool happened, so of course I tried in in V1.41… It worked!
You all probably know this already, but my normal use in the Navigator is to select zooms (occasionally) or move about the image.
So what’s the tip?
In Grid View, click and hold on the image in the Navigator. The selected image will jump to Loupe View for as long as you hold down the mouse. On release it goes back to Grid View.
A modifier to this is to Command Click (Control Click on PC) on the Navigator. The image will then open into Loupe View.
