19 * @brief Disobedience settings
21 * Originally I attempted to use a built-in rc file to configure
22 * Disobedience's colors. This is quite convenient but fails in the
23 * face of themes, as the theme settings override the application
26 * This file therefore collects all the colors of the Disobedience UI
27 * and (in time) will have a configuration dialog too.
