Adding More Functionality to the Copilot Window

Ability to copy or download the current conversation session.

Support separate windows for Document Assistance (PIKA) and Copilot/Co-worker interactions, rather than combining both in a single window.

Allow execution of basic slash commands, such as /clean to start a new session.

Provide more detailed information when issues occur. For example, messages such as "The chat was interrupted. Please try again." should include additional context explaining the reason for the interruption.
