GNOME has no thumbnails in the file picker (and my toilets are blocked)
The file picker is the pop-up box thingy that appears when you’re opening a file, usually when uploading something online. The GNOME desktop environment uses the file picker package GtkFileChooser. This file picker does not have a thumbnail view. It is broken software. Thumbnails are not a cute little extra, they are essential. This is as bad as a file picker that doesn’t list the name of the files, only their creation date, or inode serial number. It is broken software.
Personally, not a big deal, but fair point.
