# Feature Request: Global Default for Session Container Type (Branches vs Worktrees)

## Summary

Allow users to set a global default for whether new projects use **local branches** or **git worktrees** for session management, rather than defaulting to worktrees every time.

## Problem

When adding new repositories to Copilot CLI, each project defaults to using git worktrees for session isolation. Users who prefer working with local branches must manually configure this per project. For users managing many repositories, this becomes repetitive and tedious.

## Proposed Solution

Add a global user preference/setting (e.g., in app settings or a config file) that lets users choose their default session container type:

- **Git Worktrees** (current default)
- **Local Branches**

This default would apply whenever a new project is added to the app. Individual projects could still override the global setting if needed.

## Benefits

- Reduces repetitive configuration when onboarding multiple repositories
- Respects user workflow preferences out of the box
- Simple to implement as a user-level setting with per-project override

The issue names no files, tests, or entry points. Start by locating the app's project settings and session-container selection flow; done means a global choice between Git worktrees and local branches is applied to newly added projects while preserving per-project overrides.
