Previous/next image with mouse scroll wheel in the Preview pane
It would be really comfortable to use the mouse wheel (or the trackpad scroll) to step back/forward in a photo collection, alternatively to the arrow keys on the keyboard, like in the Windows Photos app or in the old Google Picasa is.
My suggestion is: when the pointer is placed over the Preview pane, interpret a scroll up as "Previous image" and a scroll down as "Next image". Currently the mouse wheel does nothing.

I would have assumed this was a standard behaviour. Odd.
Currently mouse roll is used to scroll up / down content panel when there are more images than you can see on display.
