Partly due to the way CMYK TIFFs are handled, I've been using RGB
originals with Scribus to date. To be honest, I expect to continue doing
so with Scribus - I only use CMYK images with Quark as a workaround for
its lack of built-in colour management. I'd be much happier being able
to configure colour management in one place than having to worry about
both layout and graphics tools.
Nonetheless, it'll be very nice to be able to import CMYK TIFFs when I

I've mentioned that one before, but nobody seemed to think it might be a

Sounds good to me. That should probably be configurable - and I imagine
wouldn't be too hard to make configurable. [Adds to TODO].
This looks really cool.
