How to move window buttons to the gnome shell 3.16 panel

For older versions of gnome shell, there were extensions to move the window buttons (like close, maximize and minimize) from the window's title bar to the top panel. - [Window Buttons](https://extensions.gnome.org/extension/426/window-buttons/) - [Buttons to Panel](http://sourceforge.net/projects/buttons-to-panel/) This is especially useful with windows without title bars, like [Maximus](https://extensions.gnome.org/extension/844/maximus-two/) causes fullscreen applications to be. Both do not work on gnome shell version 3.16 and seen out of active development. Is there any similar extension currently maintained?
