Profiles are split up. You now pick the agent, its login, the folder and the secrets on their own, instead of cloning a whole profile to change one thing.

Tools: set up Claude Code or Codex once, with its command and model. Give a tool its own login to run a second account (work, personal) next to your main one.
Folders: pick the folder for each new session right in the composer, from your favorites, recent folders, or any subfolder you choose.
Secrets: add API keys and other env vars once. The values stay in your Keychain, and each profile just checks the ones it needs.
Your existing profiles are converted automatically the first time you open this version. Running sessions keep the same command and folder.
Starting a session from your iPhone uses the same profiles, and the phone only lists profiles that can actually start on this Mac.
