How to merge Mutiny MATE into the top Title Bar (Like Unity 7 used to save screen space)

I have a question about Ubuntu MATE using the Mutiny Appearance configuration.

When I maximize my terminal or LibreOffice, it still leaves the title bar.

not merged into the TOP PANEL. How can I merge it? In the old Unity 7 Ubuntu 17.04, it used to merge into the top bar.

Can this be done with MATE?

Do you guys have any ideas or tips?

Solution 1:

Open MATE Tweak and check "Undecorate maximised windows" under Windows.

Warning: Title bar of a maximised window will vanish completely. You won't see window control buttons (close, minimise, maximise) for maximised windows. You'll have to use keyboard shortcuts.
Most probably Ubuntu MATE 18.04 will have the window control buttons.
