Which feature can be used to view all Indicators used by a widget and all of the Tabs a widget appears on?

The correct feature for viewing all Indicators used by a widget and all of the Tabs a widget appears on is Dependency Assessment. This feature is specifically designed to analyze and list the dependencies of widgets, including the Indicators associated with them. When you use the Dependency Assessment, you can gain insights into how widgets interconnect within the platform, allowing users to see not just the widgets in isolation but also how they contribute to and interact with other elements, including Tabs.

This understanding is crucial for analytics, as it enables better maintenance and management of dashboard components. Users can thus ensure that all parts of their analytics landscape are functioning well and provide the necessary data to stakeholders. Ultimately, this fosters a clearer overview of how information flows through the system, enhancing the decision-making process and operational efficiency.
