For more than 15 years, the FreeDesktop specification for thumbnails has included a section about the so-called Shared Thumbnail repositories[1] - a method to store the thumbnails alongside the original files, specially useful for shared network-based directories. Recently I found that no single file manager in linux implements support for such piece of the specification. In the case of Gnome, I at least found this open merge request[2], although it seems to be stalled. But I found nothing for Plasma. :-( [1] https://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html#SHARED [2] https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1548
This would fix Bug 411919.
