On the LR iPad App, I can move forward/backward with the keys on my keyboard in full screen mode, but the zoom is reset when I move forward/backward to "fill screen".
So, I honestly can not really judge the detail quality of photos in this view sufficiently and need to seem on after each forward/backward again. I always take series of photos and select out the best one, often based on detail quality. So it is very cumbersome to need to zoom in again.
It would be extremely helpful for swiftly checking photos when being able to stay "zoomed in" while moving forward/backwards using the keyboard. E.g., using shift+right/left key instead of just right/left key?
