Yes. Don't use the same name for the main menu and another application menu, 
it's a bad idea anyway (on OS X you would end up with two items with the same 
name in the menubar). Incidentally, Apple calls their equivalent of your 
'Terminal' menu 'Shell' in their Terminal application (and have historically 
done so already in the NeXTstep days).
