Hi,
I think it would be very nice to able to set the update/refresh rate of the frequency graph in the image. As it stands, it seems to refresh at like 15-20 frames per second, possibly even less, which makes it kinda stuttery. Obviously higher refresh rates would incur higher CPU usage, but I'm sure a lot of users like myself are willing and able to do that sacrifice to get silk-smooth animation.
Thank you for such a wonderful music player!
