though lowlanders request is old, it's still a very good one. (i remember that there where several other threads regarding this topic)
it would be a great improvement if the #s get their own column (especially for playlists and "now playing")
think about it: if the #s are in their own columns it could even be possible to sort the "now playing" window (and playlists too) by clicking on the column headers of the listview without changeing the song order permanently. if the user then drag&drops something, the order could be saved. this would make reordering "now playing" and playlists much easier.
one thing i just noticed: viewing the tracks in most nodes (eg. artist) there is no number in front of the title, but if you view songs through Artist-<Artist Name>-<Album Name> there are. which i find rather akward since those numbers are the same as <Track #> which has its own column and should therefore be used.
btw. regarding "fixed" issues: read this thread
, "fixed" since 2.3
