I have a large list of Keywords that is not ordered. I added a Keyword named People and will eventually move all people I have named there. The same goes for Animals, Places, etc. etc.
I find it pretty cumbersome and a slow process to drag each Keyword through the long list with a lot of slow scrolling and finally dropping it at its parent Keyword. If I at least could enlarge the keyword list it would save me plenty of time. ( Maybee there is a way to enlarge the list window, but I don’t know it and have not found it…)
Until the request has been implemented, you could change monitor settings to make the list bigger and easier to modify. Nevertheless, I’d also welcome a possibility to import a keyword list, e.g. from Lightroom or any other app that can export their keyword lists.
Depending on how many root keywords you’ll have and the depth of the list, you could modify sidecar files to make DPL import the modded keywords - which will not be less of an effort.
Eventually I found the settings dialog and changed a couple of setting in the hope of writing to sidecars and, in so doing, I found the list of permitted hierarchy delimiters.
Even with the setting to write to XMP sidecars supposedly set, I got an XMP sidecar produced but it didn’t contain any keywords - this continued to be written to the RAW file.
I have to say this is one truly awful piece of software, with all sorts of flaky behaviour like when it keeps on opening an image when right-clicking unless I hold down the right mouse button until I find the menu item I want.
And as for implying that XMP tags were being written to now obsolete IPTC-IIM - This is a product I would certainly never recommend.
