It took me forever to figure out that the interface is really quirky in that you have to enter the ID first, then hit OK ...then enter the nickname and then hit OK ..and then click "Mute this sound".

As far as I can tell, this is the only way to mute a sound with a nickname. Is there no way that you could get rid of the two "OK" buttons so that a person just enters the ID# and the nickname and then clicks "Mute this sound"? Right now it just seems a lot more complex than it needs to be.
