Hello,
After submitting this feature request by email, I've just noticed this thread. Are there any updates on this?
Saving to CXR a single image or an image-sequence, and then using Image Editor is an amazingly productive archviz workflow. As others noted, having the ability to save CXR from Picture Viewer would be a major milestone, opening doors to e.g. use RebusFarm and more. I think it really should be on top of the priority list.
Thanks in advance,
Márton Lente
