Themes in Noto

Noto has a flexible theming engine that allows you to entirely modify the appearance of the editor windows. You can also export the themes you create to files and share them, and also import theme files created by other users so you can use them yourself.


  1. In Noto, choose Noto > Preferences….
  2. On the Preferences panel, select the “Theme” tab.

Custom editor themes
