Themes, fonts and font size

dotMux is meant to be made your own. In Settings → Terminal, pick from six monospaced fonts — JetBrains Mono (the default), Fira Code, Hack, IBM Plex Mono, Menlo, or Courier New — and ten color themes: Default, Dracula, Nord, Solarized Dark, Gruvbox Dark, One Dark, Tokyo Night, Catppuccin Mocha, Solarized Light, and GitHub Light. A live preview sits right above the list, and both apply instantly to open sessions. The app chrome even shifts light or dark to match the theme you choose.

Bring your own theme

Already have a palette you like on the desktop? Import it. Under Settings → Theme → My Themes, dotMux reads Ghostty theme files and iTerm2 .itermcolors files, from Browse Files, a paste, or straight From URL (https only) — so a theme in a public repo is a copied link away. It’s free for everyone, no unlock needed.

An import is a snapshot, not a link: dotMux parses the file once, keeps only the colors — background, foreground, cursor, selection, and the 16-color palette — and stores that. Nothing else in the file is carried over (a Ghostty theme file is a full config file and can set anything; the rest is discarded, not applied), it works offline afterwards, and a source that changes later can’t touch a theme you already imported.

The right size

Set the terminal font size from the stepper (4–32 pt), or just pinch to zoom on the terminal — a transient pill shows the live columns × rows as you go. Pinch-to-zoom lives in the same settings if you’d rather turn it off.

The keyboard bar is fully editable too.
