There are other requests for viewing more than one image at the same time. I understand what’s being asked for here and agree that the current behavior of watching an image get rendered gradually from RAW is annoying. I also recognize that once PhotoLab buffers the images being viewed and compared, switching among them becomes nearly instantaneous. It takes a while and numerous attempts to switch back and forth, but it does happen. So, until images are cached/buffered in this way, what should PhotoLab do? The request here is to keep displaying the previous image (or nothing if no prior image is selected, I assume) until the next image is fully ready to be displayed with all chosen presets applied. I think I agree, since that’s what ultimately happens given enough time and attempts. And I think there should still be some clear indicator that the next image is loading.
My real hope is that PhotoLab becomes faster and more efficient in many respects.
