I don't know if it was requested earlier, but I haven't seen change on BSPlayer.
well, what me and most people would thank is when you drag a file from windows explorer, you could drop it any position on Playlist, not just at bottom of it.
moreover, you can only move one one item at time inside playlist, you can't select a group and move them.
I manage huge playlists (300+ items) and sometimes I need to update it; it's weird to put new files at bottom and manually move one by one from bottom to the position I want.
BSPlayer is one excelent player, I'd appreciate my request would be considered.
