cmux customization
What it does
- Custom actions: define reusable actions in cmux.json. Actions can appear in Cmd+Shift+P, surface tab bars, shortcuts, and the plus-button right-click menu.
- Workspace metadata: use the cmux CLI or cmux-workspace for workspace names, descriptions, colors, read state, and sidebar metadata updates.
- Import, export, and reset: back up the current config, apply the smallest diff, validate it, and keep a rollback path for user-owned customizations.
- Terminal behavior: use Ghostty config for fonts, themes, cursor style, copy-on-select, shell integration, terminal keybindings, and terminal rendering.
- Dock controls: edit .cmux/dock.json in the project or ~/.config/cmux/dock.json globally. Run cmux docs dock when available.
- App settings: run cmux-settings validate.
- JSONC shape: keep valid JSONC and avoid duplicate keys.
