I've been thinking about the use of the words IPTC and XMP throughout the software. From a purely semantic perspective, should the more inclusive term metadata be used instead in some cases.
For example in the Preferences, I think a section should be called "Metadata" instead of "IPTC / XMP". And "IPTC Stationery Pad" and "IPTC Info Dialog" should perhaps be referred "Metadata Stationery Pad" and "Metadata Info Dialog".
