Created attachment 5397 a quick dirty preview To save space it would be great to show the WM menu on right click it would only be useful if there is an option to remove the titlebar on maximized windows in xfwm(already possible with other wms like openbox)
maybe it would be great to set a custom action(eg toggle maximze or close) for the third mouse button
This is already working - upon right-click the window actions menu shows up.
Also there are xfwm4 themes that don#t have any buttons and no border.
