Lookout - Microsoft Outlook search plugin

Recently, I got to know about that Microsoft has acquired Lookout, frankly speaking I never heard about Lookout until this news.
I saw the Lookout website and found that it's a very good search plugin for MS Outlook. I downloaded it and started using, it's damn fast and saves loads of time.
I guess, Microsoft would add more features and values to the plugin or use the algorithm in coming version of Outlook.
It can be downloaded from here.
