Wondering if your download is actually moving, or if a call is about to drop? Synapse's Network Speed Monitor sits quietly in your menu bar and shows real-time upload and download throughput at all times. The moment you lose your connection, it switches to a clear 'No Connection' indicator, so you know immediately without opening a separate app.
