Here is a New Metacity Theme, “AzyCraz-3.0-metacity” with all six buttons. Theme has all six buttons, Menu, Stick, Shade, Min, Max, Close. I use the Cinnamon version of Linux Mint. When I had both the Overview Workspace and the Menu icon active they would overlap or be one under the other. I fixed the overlap of buttons. Workspace Overview button and all six buttons can now be used at the same time without buttons overlapping.
I can make other color theme if wanted.
