I am getting quite lost trying to Filter or Browse IPTC fields because they do not properly follow the category and field names used in the Metadata dialog box.
Would it not be better to arrange and name the filter and browse IPTC items to exactly match those in the Metadata dialog box? I have fields displayed in the Metadata dialog box which do NOT appear anywhere in the Browse / Filter IPTC fields. Some items do appear but reference other Metadata fields (Copyright is one).
In the attached screenshot you will see my name entered into two fields (Creator/Photographer and Copyright). These two fields come from the camera and I did NOT add them manually and they appear nowhere else. In the Browse section you will see that my name appears under Copyright and under Byline. So the confusion is how does this all tie up and which Browse / Filter fields correspond to which IPTC fields in the Metadata dialog.
Please consider aligning these labels.
