Display Folder.jpg on folder if available

Hi, sorry if this is in the wrong place, but I have a suggestion for the files app and have not found the category for thisā€¦

However, my idea was to have an option to show a folder.jpg or similar on a folders icon if the folder contains one. This would be neat to visually classify the content very fast if desiredā€¦

Ideally in the settings we have a list of filenames that should be used for this, that way we could use album.jpg or cover.png as well

My nextcloud does this. You need the preview generation app to generate the thumbnails.
