Most of my day is Claude Code and Codex now, usually four or five sessions at once. The thing that kept biting me was typing a prompt into the wrong pane and watching the wrong agent start working on it. So in lmux you hover that prompt and click ×, and Claude Code rewinds to just before it. The session keeps running, nothing restarts. The ✎ button does the same but puts the prompt back so you can fix it and resend. Everything else got added the same way, one annoyance at a time: a sidebar that shows which agent is running, waiting on you, done or failed workspaces, splits and tabs that all come back after a reboot, sessions included Korean input that doesn't break while composing (I'm Korean, so that one was for me) it's a 25 MB native app and sits near 0% CPU with 20 workspaces open I open-sourced it two days ago. It's had about 65 installs so far, and two teammates already sent PRs that went out in 0.1.1 today, which was a fun surprise. It's free and MIT, macOS 14+ on Apple silicon, built on libghostty. https://github.com/sooftware/lmux If you try it, tell me what breaks or what you'd want next.   submitted by   /u/sooftware-ai [link]   [comments]
