Opus allows you to govern this in two places, depending on what you want: locally in the current Folder Options or applicable Folder Format, and globally in Preferences. The Folder Formats option allow you to show hidden/system files in some Formats but hide them in others. The Global Preferences setting trumps everything and always overrides the Folder Options/Formats option.
You can use this command button to quickly toggle the global Preferences option.
