I would also like to stress the importance of CMYK.
The color loss when converting from RGB to CMYK is severe in some renderings, especially with magenta. This requires additional time to recover, in many cases, the vibrance of the image. If you have any recommendations of working in a different color profile, that is closer to lossless when converting to CMYK, it would be greatly appreciated.
Most of my work is in print. I realize that adding this feature may take time to implement, I just wanted to add my two cents about the importance of adding this mode for print work.
If it requires an additional charge I would be happy to pay it.
Your program is exceptional, and you consistently improve it. Thank you!
