Forum suggestion: "Topic Review" while making posts?

So, I've been using the forum for a bit lol just two days and I'm thinking that a feature that could come in handy is a "Topic Review" section on the "new post" page that gives posters a glance at the last x-number posts in a topic. I've seen this used on Charas Forums (an RPG Maker forum) and ANN's forums, and it's pretty handy.

Provided it must be a pain to program, but this is the suggestion forums so...
