Menu of open documents

MuseScore badly needs a "Windows" menu, as it were, like other Mac apps (whether it's on a Mac or not). I usually have a dozen or more scores open, and it's very difficult to know what's there without painstaking horizontal scrolling. What's worse, if you open (from outside the app) a score that's already open, Musescore doesn't take any action at all, from which one must infer that you have to look for it among what you've got.

There ought be (callupable) a traditional command menu of open documents. Or maybe it's hidden somewhere and I missed it .....
