Worktrees
Add a worktree
Repository › New Worktree…. Start it from a local branch, a remote branch, or a new branch at a commit, and pick its folder.
Manage worktrees
Worktrees are listed in the sidebar. A worktree's context menu offers Open as Repository, Lock… (with a reason), Unlock, Remove… and Prune Missing Worktrees. Removing asks first when the worktree has modifications, is locked or holds submodules.
