I would like to copy MULTIPLE layers (Typically all of them) from one PSD file to another, in one single step, rather than one at a time manually, which is what I'm doing now. I have several PSD files, each generated from a separate PanoTools stitch, and I like to generate one file that has all the separate layers (many many layers) at the end. FWIW, I'm investigating how to take better advantage of multitiple processors to stitch panoramas, since i'm impatient. By running two instances of PTStitcher, each with a separate set of source images, the whole stitch takes half as much time, but then I have 2 PSD files to be merged by copying one layer at a time, which is a bit manual. For small numbers of layers it's not bad, for for a larger panorama could bet tedious and errorprone. Thanks in advance for any ideas.
