This plugin is handy for adding reviews. I'm using it on my own personal site to track and review the various plugins I use on client sites. It helps me catalog them and give myself handy notes.
This plugin is all through shortcode, there's no GUI for it. That is a bummer and the main reason I didn't give it 5 stars. I'm not knocking the developer for this, though. This is an intuitive plugin and does what it says.
Two requests for a future update (besides the GUI if that's possible): easy CSS & template customization AND the ability to use N/A (Not Applicable). There's a plugin I just used called GigPress that makes customization SO easy. I'd use their method as a model. As fro the N/A request, I can imagine many circumstances where certain review categories wouldn't apply and it would be nice to have consistency throughout your reviews. So it would be a nice feature to have that and it not impact the overall score.
Nice plugin, though.
