I was thinking what i would love to see in Guayadeque.
1. A-B repeat # very useful for learning music by ear (very few players got one)
2. Tablatures # also useful for learning music, or just fun (like plugin for Lyrics)
3. LV2 support # there is no music player that supports LV2(i don`t now is it even technically possible), but would be awesome if we could load plugins like loudness meters, eq`s....
