You can see when entities are dormant now (this means they're out of your client's PVS). Entities can define which icon is shown next to them using the Icon attribute.
The colours here show which realm they're in. Yellow means clientside only, blue means serverside only, green means both your client and server has the entity.
The entity's owner is shown on the right.
