It would be really sweet if I could loop wav files (primarily forwards), as mentioned in the notes of the function list. It would be highly appreciated. I'd really like to put it to use on some environmental ambience sounds I'm using.
Also, being able to pause and resume a wav would be nice. and if you're feeling really generous you can maybe add a readable 'Current Time' for sounds, to show where you are in the song and be able to jump to that time.
