Final answer:
For a single-stream dashboard focused on cases, you can add a tile showing the count of open activities and a stream that displays a view of open activities. These components are most relevant for case management and activity tracking.
Step-by-step explanation:
When creating a new single-stream dashboard and planning to filter the dashboard based on cases, you could add two components which would align with this functionality.
First, you can add a tile that shows the count of open activities. This tile would provide a quick summary of the activities still in progress and can be used as a metric to gauge the workload related to the cases.
Second, you can include a stream that shows a view of open activities. This stream would allow the dashboard user to see a more detailed view and directly interact with the current activities associated with the cases.
On the other hand, a stream that contains a public queue of cases could be relevant if it focuses on the case data you're interested in, and a chart based on open activities could be useful if it is specifically reflecting the metrics and trends of just open activities related to cases.
