"New Window" keyboard shortcut in Safari [closed]

Question

I'm using macOS Sierra (10.12) and Safari 10.0.

I usually just press ⌘N to open a new window in Safari. This shortcut seems to have changed recently (perhaps when I upgraded to Sierra). Now, ⌘N will only open a new window in non-full screen mode. In full screen mode it will open a new tab instead.

I checked under File in the menu and it displays the shortcut ⌥⌘N for New Window when I'm in full screen mode. This command works in full screen mode but if I'm not in full screen mode ⌥⌘N will open a new tab :S

I tried setting ⌘N as a keyboard shortcut for New Window in Safari (in System Preferences). Now it also says "New Window ⌘N" under File when I'm in full screen mode but the shortcut still opens a new tab.

Is this a bug or is it supposed to be a new feature? It doesn't seem to work very well. I would like to have a keyboard shortcut that opens a new window regardless of whether I'm in full screen mode or not.

Note: ⌘T seems to work the same way as before.
