This is really helpful! Thanks!
Additional question. I recently moved to C1Pro 8.3 for my raw workflow and tethered shooting. C1 can read the changes in color or star rating, but not the other way around. I have set C1 to always sync metadata changes. But when I change the color or star rating in C1, PM doesn't see it and C1 always changes it back to whatever PM sees...
Any idea how to change that?
