As part of preferring an embedded XMP only workflow (to do with using Android to also update synced photos metadata) it would be great to be able to use XMP fields as thumb labels.
When searching for this I found a previous discussion that suggested it was not possible, but I believe from a number of years ago.
As XMP fields are able to be chosen in the batch rename tool, I wonder if the situation has changed and maybe now XMP could be implemented for thumb labels.
Having tried lots of photo tools over the years, and with many of them being very good at certain aspects, I always come back to XNViewMP as it does the vast majority of what I need. The above would be the cherry on top of the cake if it could be implemented!

Thanks,
Marc
