Block Cursor in Sublime Text 3

Seems so simple, and would be nice if it was a one line setting or solution, but after searching forums, I found a pretty easy fix.

Add this code to your settings file:

"caret_extra_bottom": 0,
"caret_extra_top": 0,
"caret_extra_width": 8,
"caret_style": "phase",

And you will get a cursor like this:

Adjust the width to your comfort level. I like 4.
