One thing that is not mentioned in thread yet is the missing ability to quickly distinguish different media types in a Details view that contains imported music and image files (sometimes music videos too). In use all media views a lot. I have tagged my album related images and videos with the same artist, album and year tags as the music files have.
Same here....
I agree that icons showing the difference between file types are very helpful (it's much easier to glance through a database this way than having to use the File Type coumn itself to distinguish between basics of image/video/music/document)... and having a color (blue/gold) indicate whether or not a file has been imported is also nice.....
