In the GitHub Copilot desktop app, I would like every new session created within a project to provide an optional right-side file explorer.

Currently, the right-side panel appears to be available mainly after opening a file or a diff. When starting a new session, there is no convenient way to browse the project’s files and inspect the code context before sending a prompt.

Please consider adding a toggleable project file explorer that is available in every project session. Ideally, it would:

• Show the file tree of the current project/worktree

• Allow users to open and preview files

• Support file search

• Remember the panel’s visibility and width across sessions

• Remain independent from the diff or terminal panels

This would make it much easier to understand the project structure, review related files, and provide better context when starting a new session.

Start by examining the /chat session UI and how the existing file, diff, and terminal panels are presented. Compare the requested project/worktree file tree, preview, search, and persisted visibility and width behavior with the current session experience; done means a toggleable explorer is available in every project session and remains independent of the other panels.
