Connect the git sources your workspaces branch from, keep them all visible in the sidebar, and disconnect one without losing your clone.
A repository is a git source you've connected to Cohalen: your own clone on disk, or one cloned from a remote. Every workspace branches from exactly one repository.
The sidebar lists them all at once, each one a group of its workspaces, so parallel work across projects stays on one screen.
Two ways in, and you pick one per repository.
Open connects a folder that's already a git repository. Pick any folder inside
one and Cohalen connects the repo root. If the folder isn't a git repository,
Cohalen offers to initialize one. It never runs git init behind your back.
If the folder you picked sits inside a larger repository without being its root,
Cohalen asks which one you meant. That way a stray .git in a parent directory
can't hijack the connection.
The connected list is a set. Connect one that's already connected and Cohalen reopens the existing entry rather than adding a second. A workspace's own folder is a worktree, not a repository, so Open turns it down. Connect the repository it came from instead.
Each repository group shows its active workspaces, with an expandable History of archived ones underneath. Open one and it moves to the front of the list, so the projects you touch most stay near the top.
A repository whose folder no longer resolves on disk shows as Missing. Nothing disappears quietly.
Relocate points the same record at the folder's new home, keeping its workspaces and its place in the list. Renaming a folder is a relocate. If the source is gone for good, Forget removes it.
Forget drops a repository from the connected list. Cohalen reclaims only its own scratch: the worktrees under its managed directory, and the branches it created for them.
Your working copy and your own branches are untouched, so you can reconnect later.
