From project management, you surely know the traffic light indication function. This plug-in offers a simple traffic light, you can represent anywhere in your blog. As dashboard wigdet, as sidebar widget and as shortcode. Maybe you find something meaningful where you can use it. Normally critical is red, average yellow and good is green. But what do I tell you. I’ve never seen this before into WordPress. I think this is so funny about it. I try to get it to the WordPress plugin repository but I’m not sure if they accept it. In this first version every logged in user can change the color by simply clicking on it. For this page I made an extra version, where you can change the color by clicking on it also as non logged in user. WordPress accepted it!
