I’ve been looking for something like this, but closer to the Claude Code philosophy of a strong, terminal-first workflow. What I really want is a "Claude Code Manager" that can spin up new git worktrees, manage multiple instances, and let me jump between them - no heavy UI abstraction.

I’ve noticed these UIs tend to strip away native features (plan mode, sub-agents etc.). A thin layer that preserves Claude Code’s built-ins while orchestrating instances, worktrees, and branches from the shell would be ideal for me.
