My current workflow:
1) choose photos in Digikam, copy them to another folder
2) open photo in RawTherapee
3) try to get good colour and contrast in RT, fix highlights, etc,
then export to Gimp (RT has no layers)
4) use RGB curves in Gimp, sometimes decompose to RGB and combine
layers to create

Hi. Although it's a good idea to have the separate- plugin bundled in
default GIMP installation, I'd like to discuss some enhancements that
could be done in its bigger brother Separate+ to make it more
functional for people who needs more advanced CMYK usage.
The idea is quite simple and wouldn't
