Increase spacing between words

In all courses on KA, the text format used is extremely inhibitive to learning.

Specifically, this is because there is not enough white space in between words, making it much more difficult for the eye to separate one word from another (i.e., sentences look a like a solid block of letters.) Compare KA's text to any professional book's text, and you immediately recognize the difference.

In preferences, please allow the user to define their own word font and spacing. 

Thank you!
