Please add an option to timeout notifications from the same person or group within a small window of time. When someone/'s sends several messages in a row, I don't need 15 bzzts or dings in a 4 second window. The option to say, for example, once a message is received, silence alerts from that source for the next 5 seconds. The notification can still show(if that's a controllable thing) but no physical/audible indicator.
