Version: (using KDE KDE 3.5.0) Installed from: Slackware Packages OS: Linux I'm mostly using KPDF nowadays, and the addition of fonts to the properties is brilliant. One nice and - for some people - useful feature would also be to add the colour model used to properties. It can be useful to check if it is a CMYK-PDF or RGB-PDF, especially when you check a file before sending it to printers. Presently, I use imagemagick's identify commandline tool for this - but it would be very very nice to have it in KPDF (maybe just as a frontend to imagemagick's identify?).
This isn't likely to be implemented for KPDF, since development has effectively completely moved to okular. It is a potentially valid wishlist item for okular (and perhaps poppler) though. I take it when you say "colour model" you are just looking for the colourspace (i.e. RGB or CMYK), not the full list of things that imagemagick can provide?
