Ubuntu 16.04 - Add Borders To Windows

One of the changes I noticed most from switching from Ubuntu 14.04 to 16.04 was the lack of borders, and use of shadows on windows. Initially, I thought this was pretty neat, but having black terminals that disappear into each other bothers me too much. Thus, I decided to restore the border.

To see the difference, compare the images below:

Steps

Edit the file at /usr/share/themes/Ambiance/gtk-3.0/apps/unity.css

sudo gedit /usr/share/themes/Ambiance/gtk-3.0/apps/unity.css

Near the top, change:

    -UnityDecoration-extents: 28px 0 0 0;

to:

    -UnityDecoration-extents: 28px 1px 1px 1px;

Then log out and in again.
