Window buttons in panel for maximized windows don't respect org.gnome.desktop.wm.preferences like normal windows do.

do a command like this in the terminal:
gsettings set org.gnome.desktop.wm.preferences button-layout 'close:'
this should get rid of all minimize and maximize buttons on your windows. except this doesn't work when the window is full screen. a full screen window should follow this variable setting also.
