I have a custom Storage Template set and I've confirmed that it's been correctly saving into the folders and filenames I've specified but when I look at the image file details info (metadata) I see what I think is the original filename, before it got updated to the storage template format.
I'd appreciate the option to have the file info metadata name match the actual name of the file.
One example I've seen this become an issue for me is in the Findich.app (accesses photo library via the MacOS Finder), where all of the metadata names show up as the file names in Findich/Finder window. I'd much rather they show as the actual current filenames.
