My favorite cmux feature is Cmd+Shift+U. I have 17 workspaces open right now, each running an agent. I used to click through tabs and macOS system-wide notifications to figure out what completed. But with cmux, I can just "Cmd+Shift+U" Cmd+Shift+U jumps to the newest unread notification. In practice that means the last agent that finished. It switches to the right workspace, focuses the exact pane, flashes it so you see where to look, and marks it read. If the notification came from another window, that window comes forward.

Introducing cmux: the open-source terminal built for coding agents. - Vertical tabs - Blue rings around panes that need attention - Built-in browser - Based on Ghostty When Claude Code needs you, the pane glows blue and the sidebar tells you why. No Electron/Tauri. Just Swift/Appkit.

Introducing cmux SSH: `cmux ssh user@remote` You can now drag images into SSH'd Claude Code sessions, and cmux will automatically upload them via scp. And when you start a dev server on the remote machine, the browser pane in cmux can reach it at localhost:3000 without port forwarding. The workspace kinda becomes the remote machine, so split panes/new tabs automatically open remote shells. Out in the latest version of cmux (0.63).

Introducing cmux Fork cmux Fork Conversation lets you branch Codex/Claude Code/OpenCode/Pi/Hermes... threads to new tabs, new splits, and new workspaces It's pretty useful for exploring multiple directions in parallel, or if you want to have multiple Claudes with the same context work in the same directory (works surprisingly well) Right click anywhere in the tab/terminal or Cmd+Shift+P -> "Fork Conversation to..." Out in v0.64.19
