Ability to expand and view a whole testimonial without clicking through to the testimonial detail page

It would save a lot of time if we could expand (e.g. by clicking a ‘Read more’ link) to view a whole testimonial from the dashboard page, without having to click through to the testimonial page itself. When approving lots of reviews, it adds time when having to click through to the review to read the full contents, and then click back to the dashboard and find where you’d got to.
