Is there a way to have an image reference side by side with the image you are currently processing?

Thank you for the quick responses. Yeah, actually something like the culling mode in the darkroom would be what I was looking for… pity. I don’t know how hard something like a side by side view for snapshots would be to implement, or if it is even of interest to the devs, but that would really be handy to me. Perhaps in the future.
