I work through folders containing hundreds of images and would find it easier for me to keep track of where I am if I could as part of the export module add either a color or star rating as part of my export preset. I use the lua script to save the files the collection already.
This is probably not a big deal to other users so I am reluctant to put a feature request in for something most people would consider trivial or frivolous.
I recently thought that it would be nice if the export settings would be stored as metadata. For example, I have an export to piwigo and currently always tag these photos manually that I have exported them into the gallery.
No not the modules that were used in the edit, it would be great if I would know with which export preset I have exported, for example, to my piwigo instance, to a file etc…
I guess that could be generalized to add any kind of metadata on export, not only tags but also rating, color tag etc…
