Metadata - merge all Edit dialogs into single one
IPTC/XMP Metadata with user-defined Tab
but they sound like a lot of work. I would be happy if:
- "Object name" were renamed "Title" in the XnView dialog "Edit IPTC-IIM"
- The field were moved to the first, "Caption" tab of the dialog (together with the other popular fields, "Caption" and "Headline").
Please refer to the IPTC definitions here and here.
