P: Prevent mouse wheel from navigating to another image while editing
While editing images I often use the mouse wheel to scroll between edit panels. This has become more important with the advent of HDR - the "Light" panel is now quite long if you are using Curve and SDR settings. The problem is that, if the mouse pointer is just slightly outside the edit panels and you don't notice, moving the wheel takes you to another image. This is infuriating when you are focussed on what you are doing - it breaks the flow.
I would much prefer it if operating the mouse wheel while editing did not navigate to another image. The cursor keys provide this functionality anyway, and they reliably move one image at a time - moving the mousewheel may move any number of images depending on how far you move it, so you end up on a random image. I don't think using the wheel to navigate between photos while editing adds useful functionality, but for me it has a big downside.
If there is evidence that people often move between images with the mouse wheel while editing, then maybe make switching that functionality off an option; otherwise I would say just disable it.
