Created attachment 111917 [details] TextPreviewFolders Not sure if this is the right behavior, but upon selecting preview text files for the desktop, the desktop icons that I have turned to text previews. It is understood that there are text files in the folders but not sure if turning the folder icons to previews is well understood. Let's change text files to show previews, not folders.
Technically, Home and Trash are .desktop files which are plain text files but I agree it those are typically used for links and application shortcuts so them being trated as text file is unintuitive.
