As I was preparing to backup up my system today I noticed a new root level folder called /TemplateFolder (containing a single file, ImageIngester-IPTC.xmp) that had been created when I executed IIP 3.1.03 for the first time yesterday. I renamed the folder then executed IIP 3.1.03 again and sure enough /TemplateFolder reappeared!
I already have the exact same ImageIngester-IPTC.xmp installed in ~/Library/Application Support/Adobe/XMP/Metadata Templates/ so I'm not sure why creating the /TemplateFolder is even necessary?
Another bug fix for 3.1.04?
