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