Hi all, Working with Andrew’s "spacer" situation, I see now that my staff layout functions can be simplified significantly: since every break "must" be accompanied by a bar (even if it’s an invisible one!), one can simply use that interface (and no others!) to force visibility.
In the snippet below, you can see the effects of forcing visibility (\showStaff), forcing invisibility (\hideStaff), and reverting to normal (\resetStaff). Note that these functions can also be used with \once, if desired (though I haven’t in this snippet). Hope this helps!
