Add "Export" button to file operations toolbar
OS: Linux Mint 20.1, Arch.: x86_64, MuseScore version (64-bit): 188.8.131.528021370, revision: 3224f34
Other programs such as LibreOffice have a "Print Pdf" button on the toolbar as default. So, it seems reasonable for MuseScore to provide an "Export" button on the toolbar, or, at least, to enable this as an option for the user.
