hello back! I've set up `gtk-application-prefer-dark-theme=1`in */etc/gtk-3.0/settings.ini* (I've edited system-wide config since I don't have any *~/.config/gtk-3.0/settings.ini* file) I've run Geany again after I changed it but nothing has changed. This is the only message I get from the terminal:
`(lt-geany:13164): Geany-WARNING **: Failed to load custom CSS: <broken file>:1:0Failed to import: Error opening file: No such file or directory`
