Event type-based notification filtering

A method comprising:

• causing a plurality of notifications to be presented on a computing device, wherein the plurality of notifications are displayed on a screen of the computing device, wherein the plurality of notifications includes a first notification of a first event type and a second notification of a second event type that is different than the first event type;
• causing a plurality of filters to be presented on the computing device, wherein the plurality of filters are displayed on the screen of the computing device, wherein the plurality of filters includes a first filter that is associated with one or more first event types, a second filter that is associated with one or more second event types, and a third filter that is associated with one or more third event types, wherein each filter in the plurality of filters is a display filter;
• after causing the plurality of notifications to be presented on the computing device, receiving, through the computing device, input that selects the first filter and the second filter;
• in response to receiving the input that selects the first filter and the second filter:
• identifying the one or more first event types and the one or more second event types;
• identifying, from among the plurality of notifications, a strict subset of the plurality of notifications that are of one or more of the one or more first event types or of the one or more second event types;
• wherein the strict subset includes a first notification that is of the one or more first event types and a second notification that is of the one or more second event types;
• causing the strict subset of the plurality of notifications to be presented on the computing device without causing any notifications outside of the strict subset to be presented on the computing device;
• wherein the method is performed by one or more computing devices.
