Collapsed notification bubbles
This mock-up presents the idea of collapsed notification bubbles, which allow another notification — of lower priority, to appear under the collapsed one.
To keep them from being (too) distracting, it would only allow two notification bubbles to appear at a time — in which there would always be one collapsed notification bubble.
