Only create submenu if more than 1 file type is selected

Hi, I'm liking the app, don't know why this isn't built into the OS already. I think it would be nice to show submenu items in the main menu if only 1 item is selected. I managed to get this to work on my mac on the new-version branch, but I'm not sure which branch is the most up to date. Heres the code I used. I've literally never used objective-c before so feel free to change anything if you end up doing this, ha.

if (submenu.numberOfItems > 1) {
    NSMenuItem *mainItem = [[NSMenuItem alloc] initWithTitle:@"New File" action:nil keyEquivalent:@""];
    NSImage *mainIcon = [NSImage imageNamed:@"add"];
    mainItem.image = mainIcon;
    mainItem.submenu = submenu;
    [menu addItem:mainItem];
}

if (submenu.numberOfItems == 1) {
    NSString *title = [@"New " stringByAppendingString:submenu.itemArray[0].title];
    NSMenuItem *newItem = [[NSMenuItem alloc] initWithTitle:title action:submenu.itemArray[0].action keyEquivalent:@""];
    newItem.image = submenu.itemArray[0].image;
    [menu addItem:newItem];
}

I like this change, it's a good idea! So I fixed it in the new-feature branch so you'll have to run git pull for it to update automatically. If you updated it on your own fork, then no actions are necessary, but this will help future people who install the full version. Thank you so much for your input! Lmk if you have any questions or concerns
