i don't know if i can request something about plugin in the official gpsoftware site so...
it's will be interresting to display embedded album art in viewer, on top or bottom or better, we have a button in right of mp3 file field to toggle informations (type, bitrate and lenght) so add cover here.
PS: i post (by error) this request in plugin section and i'm sorry, but moving post instead of deleting would be interesting.
