compare selected pictures synchroneously
comparing a number of pictures directly in a side by side view with synchroneous zoom an pan would be great.
Some other viewers do have this feature (XNview, faststone image viewer, ThumbsPlus, ...)
This is great for comparing several similar pictures (e.g. check group portraits for closed eyes).
It would be nice if you could specify points that are synced if the images don't have exactly the same view.
