21 | * @brief Visual appearance of Disobedience | |
22 | * | |
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 | |
26 | * ones. | |
27 | * | |
28 | * This file therefore collects all the colors of the Disobedience UI | |
29 | * and (in time) will have a configuration dialog too. | |
