A Control Node is what is exposed to the user in a Control Application and allows the user to manipulate content such as text information, images, colors, and most other properties within a Composition.
Control Nodes are linked to Singular properties and are updated by control apps or the REST API. Singular Control Nodes are defined within a Composition. The scope of a Singular Control Node is limited to the app instance that uses the Composition.
Control Nodes are created in the Data Interface & Control Panel
