Hi Paul,
thanks a lot for testing FerrumPix with a real photo series and for writing all of this down.
RAW or JPG only: this already works through the gallery filters. Set the file type filter there to RAW only, everything except RAW, or a specific extension such as JPG, then open an image. The Viewer only navigates through the images left by that filter, so you can review just the RAWs or just the JPGs.
Adding a keyword to several photos: select the images in the gallery, open the Info sidebar and enter the keyword there. It will be added to every selected photo, while existing keywords remain untouched. With multiple photos selected, the list only shows keywords shared by all of them, which can make it look as if the others disappeared, they have not.
digiKam metadata: FerrumPix reads ratings and keywords from the image itself and from XMP sidecars, including digiKam-style sidecars such as photo.NEF.xmp. By default, however, digiKam often keeps this information in its own database until you explicitly write the metadata to the files/sidecars. For RAW files, the relevant options are under digiKam’s metadata/sidecar settings.
Colour labels are different: digiKam stores those in its own metadata field, which FerrumPix does not currently read.
Zoom: the Viewer already has a 100% button in the bottom bar, but there is no keyboard shortcut for it yet. The arrow keys currently move between images, which is why they do not pan a zoomed image. Your three suggestions: a 100% shortcut, zooming around the image centre, and keyboard panning while zoomed, all make sense, and I will have a look at them.
And no worries, I do not read your list as demands at all. It is exactly the kind of practical feedback that is useful, and I’m glad FerrumPix is already usable for you.
Regards,
Patrick
