Front-end editing via sidebar

I'm looking to add additional functionality added to the front end of the basic wiki page. Namely something similar to what the site Giant Bomb has produced as seen on this link ( We're only looking to include "some" of the features like the 5-Star Rating system, the detail box, and possibly an image gallery, which again, can be editable via users on the front end. What uses for their plugin review system ( is exactly what we're looking for in terms of a rating system. I realize that this is additional functionality than what is offered, but I am willing to pay for this and the other functions mentioned in this post.

Thanks in advance!
