I would like to be able to define a list of sidecar files (extensions) that would be copied/moved/deleted when working with corresponding image files. A number of programs have their own sidecar files such as .dop used by DxO PhotoLab.
I would also like an option to hide or display sidecar files in contact sheets.
I do not expect PM+ to do anything with the contents of these files (except for .xmp files).
Thanks
Keith
