Yea, actually I thought about this but didn't know what to return with the mute function since function returns have to be strings.

I kind of imagined that people would just change the meter draw type in the meter properties to something like a progress bar or pie graph. Then they could just change the range of the graph so that it was 0 to 1. Then the mute function would produce either a circle or bar when the speakers are muted, and nothing when they are unmuted. That is why I return a number from the getmute function.

It would be easy to implement what you describe, though, so I'll go ahead and add the ability to choose your own return strings when I have a little free time.
