I suggest a feature to synchronize selected correction settings between the master and virtual copies.
The settings could be selected in a similar way, how we are already able to copy and paste selected correction settings from one image to another.
This would allow the following scenarios:
- I can edit one master file, synchronize all settings except the crop. Then I can create several virtual copies for several output formats, e.g. 1:1, 5:4, etc. If I do any adjustments to any of the images, these would be synchronized among all virtual copies.
- In a similar fashion, I could decide to only synchronize the crop. Then I could create for example a color and a black and white version. If I adjust the crop later, it would be automatically changed in both versions.
