Did I misunderstand the way synonyms work?
Seems Adobe misunderstood the way keywords should work. Works the same way for me. Very disappointing. Also, if the list of keywords is exported as a text file, the synonyms are missing.
In general, this seems very much a version 1, and one that was rushed out the door. Poor documentation, features such as Search and the Metadata Browser that aren't well thought out, some odd bugs, ....
Very sloppy. Not worth $US 200.
