It would be nice if the component viewer wouldn't reset to All after a new area is selected.
Also would be nice if variant selector would use the available area to display multiple images at the same time - in some intellgent way so that one knows that possibly not all variants are visible at the time.
A good idea might be to optionally add IPTC keyword of that would say that Neat Image worked on the image and what params did it use for filter settings and such.
Second that! I use the component viewer a lot and when comparing Cr reduction on several selections for instance, it would be good if the viewer stayed with Cr until I tell it to do otherwise.
