Brief: Toggle reloading of the active theme when an option is changed through the Customize UI.
Symbol: modus-themes-inhibit-reload (‘boolean’ type)
Possible values:
nil
t (default)
By default, customizing a theme-related user option through the Custom interfaces or with M-x customize-set-variable will not reload the currently active Modus theme.
Enable this behavior by setting this variable to nil.
Regardless of this option, the active theme must be reloaded for changes to user options to take effect (Enable and load).
