How to show location in Sublime Text file preview (right sidebar)?

Question

When you open a file in sublime text it shows a small version of it on the right side where you can click and scroll. In sublime text 2 it always stayed highlighted on where you are in the file, but in 3 it no longer does. I am wondering how to get this feature back, and also what the correct name for this right side bar preview thing is.

This is what it looks like in 3

This is what it looks like in 2 and what I am going for. Notice how the top of the right side-bar is highlighted a lighter gray.

Answer 1

Just add this line to your user settings:

"always_show_minimap_viewport": true

Thanks @Rico for telling me it is called a minimap !!
