Custom Star Rating to Testimonials.

Although the testimonials do not include a star rating you can certainly use the built in Glyphicons to make a star rating. Here is an example of what you would add to the Quote area.

<span class="glyphicons glyphicons-star"></span><span class="glyphicons glyphicons-star"></span><span class="glyphicons glyphicons-star"></span><span class="glyphicons glyphicons-star"></span><span class="glyphicons glyphicons-star"></span>

There are also many plugins that can provide you with advance testimonial quote bubbles.
