Problem Statement

Creating a new branch/worktree with a specific name is cumbersome and often results in claude being confused as to which branch/worktree the session should be in.

Proposed Solution

There are plenty of bug reports on how claude code on the mac app doesnt display or stiay to the session's worktree/branch, but I'd like to request similarly to how other AI coding apps work, I'd like to be able create a new worktree from the mac UI rather than only selecting existing branches or worktrees.

I also have a hunch this might help the mac app stay in that new branch rather than having to create and switch through messages.

This would also use less tokens and be a faster workflow.
