Most of propositions are restatement of the app name or theme thereof, and thus do not seem to be very helpful (everything in a notes app has to do with "notes" one way or another). Plus, having naming conventions change per app is confusing. The "file" menu is usually about "(primary) actions" and "I/O", so I would rename all of this as "actions". However, "file menu" has been associated with these kind of actions, and it is fair to consider a liberal interpretation of the word broadly referring to organisation of data (wherever this lies) and creation of new data structures within the app (not just filesystem level).
