Has View/Full Screen (673) disappeared in 674?

Hi,

I found that 673 on Windows has the feature View/Full Screen, which saves real estate by removing the decorations of the window manager. I installed 674 on my Linux notebook (RedHat 8) where every square inch counts, but the menu item is not there.

Has it disappeared from 673 to 674, or is it available only on windows, or...?

Thanks for the answer,
Nischkaa
