I am not sure whether this is the right place to post this, but our team are developing a free search software called Cleeki where Wikipedia client is one of the functions we have. With Cleeki you can:
1. Search Wikipedia with one click, 2. Read multiple most relevelant Wikipedia articles instantly (even without opening your browser)
You can visit http://www.cleeki.com http://www.cleeki.com for details and downloading. Hope this is a helpful tool for you.
Thanks, Jack
