I see why it doesn't get saved instantly to the file, but in earlier versions it worked as it should: I edit the tag, press save and the values are there to see. If I do the same in this version, it is different: If I open the tag editor from the song in playlist, it sets the display back to blank after saving (but it does get saved, you just don't see it in the editor until you open the file again). But if I open the tag editor from the library view, my input gets saved and is displayed instantly, even if the same song is still playing in the playlist. That makes no sense in my opinion.
