A similar change could (and probably should?) be implemented for
lcd_base, too - but thjis requires a little more code changes, plus
the introduction of both getter and setter functions.

Do you think this should be done?  If so, I would prepare a patch...
[Otherwise I'd save the effort...]

Best regards,
