Workspace Control allows users to reconnect to their disconnected sessions automatically when they roam between devices or reconnect after a network disruption. It is designed to provide a seamless user experience by maintaining the user's session state, allowing them to pick up where they left off without starting a new session. This feature can be managed within the Citrix Virtual Apps and Desktops management consoles and is essential for scenarios where users need to maintain continuity in their work, such as in the given scenario where users leave work and expect to reconnect to their sessions later.
