A final thought.
I was looking at @Omgitstony solution, which was right and said to self–how did @Eveready2622 miss this?
I went to the pan Scan v3 and looked at the layout. There is nothing in the UI to indicate that you should scroll.
If you are a casual user the scroll is not apparent. It just looks like four choices.
If your familiar with the camera then your memory kicks in and you remember to scroll.
Long winded way of saying an appropriately placed < and > would help the casual user.
I’m not sure that this rises to the level of a “Wishlist”. I’ll let others opine on that.
