Hi Keith,
I find that «Scrivener"s quote “management” is great.»
My only concern is about apostrophe character.
I thought a lot about it, and I came to the conclusion that if Scrivener had the possibility to set less-than and greater-than characters as « and » respectively, it would be much better, than the usual keyboard combination (that make you stop writing without looking at the keyboard) all the time long.
So, instead of transforming " in « or in », you just make the same magic on < key.
One more solution that fits perfectly for Italian language, but not for English should have hardcoded a rule that if single-quote character was not near a blank or a punctuation, than it’s not transformed in double quote, if set that way. [In English language you find apostrophe at the end of a word like in «One of the writers’ habit is to never look at the keyboard»]
One more thing. With two monitors fullscreen mode is not showing always the disappearing menu. Maybe you can make it visible with a keyboard shortcut?
