Due to market reasons I need apply to each picture iptc data in both languages English & Spanish, I use the keyword field for Spanish language and the Caption field for English, I´ve no problem with Keyword field itself when entry iptc data, no duplicated data is applied, but this doesn't happens in the Caption field. For me, and I guess for more people out there, would be really useful add a feature such as: "Remove Duplicated Keywords" option, for example next to the "Case Sensitive" search when using the find & replace tool, after apply keywords to a thousands of pictures it is really an ardous task remove manually hundreds of duplicated keywords ( just into the caption field ), with the suggested feature it will take just a couple of seconds.
Thanks in advanced for considering
