# cmux Customization Keep the user's config intact, prefer schema-backed edits, and validate before reporting completion. ## Choose the right surface | Want to change | Edit | |---|---| | App preferences (appearance, sidebar, notifications, browser routing, automation, shortcuts, new-workspace placement) | `~/.config/cmux/cmux.json` via the `cmux-settings` helper | | Custom actions, workspace layouts/commands, tab bar buttons, plus-button behavior, Command Palette entries, notification hooks | `~/.config/cmux/cmux.json` globally or `.cmux/cmux.json` in the project | | Dock controls (right-sidebar terminals: logs, test watchers, git TUIs, dev servers, queues, `cmux feed tui --opentui`) | `.cmux/dock.json` or `~/.config/cmux/dock.json`; `cmux docs dock` when available | | Terminal rendering and terminal keybindings (fonts, themes, cursor style, copy-on-select, shell integration) | Ghostty config, usually `~/.config/ghostty/config` | | Workspace names, descriptions, colors, read state, sidebar metadata | cmux CLI, see [../cmux-workspace/SKILL.md](../cmux-workspace/SKILL.md) | | Feed event sources | `cmux hooks setup` | Project-local `.cmux/cmux.json` and `.cmux/dock.json` let worktree, SSH, review, dev, CI, and docs patterns travel with the repo; project actions and commands override global entries with the same ID or name. Global app preferences do not belong there. If a request can be handled by Ghostty config, say so and use Ghostty config instead of inventing cmux UI se
