cmux

Lawrence Chen shares his adoption of Peter Steinberger's coding workflow, highlighting cmux, a tool he built to manage multiple codex agents and notify him when they finish, improving multitasking in terminal environments.

cmux now includes a better markdown viewer, allowing users to open README.md files with the command `cmux open README.md` or by dragging a file from the right sidebar.

Introduces cmux Finder, a file explorer within cmux that can preview videos, images, PDFs, and markdown files, togglable with Cmd+Shift+P.

The developer shares a personal workflow improvement using cmux, a terminal multiplexer, to manage parallel work across multiple projects and tools with better visual context and faster switching.

cmux Vault introduces a right sidebar vault pane for managing sessions from Codex, Claude Code, OpenCode, and Pi, with full-text search and drag-and-drop support, available in v0.64+.
