The only few reasons I didn't rate full 5 stars is that,
» There is a Backlink to the Developer included in the free version, and its no where discreetly stated so..
» I myself didn't get to test the module's functionality, since the website on which i installed it is pretty new and still has long way to go, to get any considerable search engine ranking/traffic.
» Theres no link to an actual/working demo.
And now to the Reality,
The developer must be lauded/appreciated for the efforts he/she has taken & the work he has done, since its free.
And also, in my opinion this module is based on an excellent idea, having very few similar extensions on JED.
And users like "mickles" should learn how to show some appreciation to the devs, and if an extension doesn't meet a specific requirement(which the extension never claimed to) of a user it doesn't mean that it deserves low rating.
Thank you developer.
