The two new Playlist Viewer Track Display options are really great! I propose that the two original settings - "Track Name Only" and "Full Path" - be slightly renamed for greater clarity and specificity in the new list of settings options. Here's what I suggest:
Track File name
Track File full path
Title & Album from ID3 tags
Title from ID3 tags
(I'm not confident re which words should be capitalized and which should be lowercase.)
