I wish that file managers like #dolphin and #nautilus would thumbnail files based on their File Unique ID and not path, I have 150GB on 650 files from my photo shoot and the thumbnail generation takes a lot of resources where the thumbnail is thrown out when I rename the directory, or move the file into a sub-directory which can take 10 minuets just to create thubmbnails.

Also, when someone makes a #systemd #kio thumbnailer to automatically thumbnail paths let me know as it would really speed up my workflow to have the thumbnails ready to go when I enter the directory.
