This article also applies for Linux Mint 18.1 Mate and Linux Mint 18.1 Xfce.
We installed i3wm following this article on the newly released Linux Mint 18.1 Cinnamon.
Since the latest article about i3wm, I added a shadow around the windows and some transparency to windows that are not focused.
Compton.conf file in ~/.config/i3 is taking care of that. Special code had to be researched in order not to show shadows around the conky’s as well.
shadow-exclude = [ "n:e:Notification", "window_type *= 'normal' && ! name ~= ''" ];
Showing you the effect of the transparency and the shadows.
