Map containers can be one of of two forms:
- notes containing other notes
- agent that contain aliases to any note matching the agent query.
To help differentiate these two different types of containers, they are given a different visual render:
- normal containers show their title area at the top of the icon above the viewport of the container's contents.
- agents show their title area below the viewport.
This difference is replicated in Outline view icons whereby containers have a thick bar at the top if the icon and agents have it at the bottom of the icon.
