I just mean png and svg are quite inefficient by 2020s standards, and avif, webp, heic, heif, jxl support are already universal even on fresh installs in other applications. It would really be a great and much appreciated feature
A recent dependency was added to enable Dolphin to display thumbnails of .avif , .jxl , .webp , and other image formats.
But you’re confusing ‘Folder Icons’ with ‘Thumbnails’ aren’t you?
You can set folder icons through the Properties window… but there are limits as you say…
