The Scope node is a scope inside which many nodes can be inserted and can be collapsed into one node. The node can be collapsed and opened by selecting the Scope and clicking on the 'Collapse into node' icon in the tool bar of Quantum Composer, or by pressing cmd+b or ctrl+b. New boundary nodes can only be added when the Scope is fully uncollapsed (ie. new boundary nodes cannot be created by just unfolding the node temporarily by clicking the arrow at the bottom of the Scope)
The node does not have any specified inputs. However, if there are nodes inside this scope, those will require inputs that have to be dragged inside or be outside with connections on the boundary of the scope.
A scope node contains the nodes inserted inside the scope. The input and output of these nodes can be connected to other nodes outside the scope from the walls of the scope.
In the example below, the Scope node is being shown in the collapsed and the opened setting. The advantage of the Scope node is that one can display only the desired information and hide unnecessary details. This can help either to reduce the cognitive load as the flowscene is opened or if a user would like to interact with only a few parameters, and all the nodes may not be relevant to look at.
