It is a very good quick link for Twitter addicts like me. There are 5 default topics set for seraching tweets- Google, Yahoo, Twitter, Chrome, Java. Clicking on Options link at the right top corner of the popup will take you to the settings page. Here you can change the 5 default search topics to your custom ones. Once you save them your topics will appear on the tabs. clicking on tab will show the respective related tweets. Latest 15 tweets appear in the list.
The best part I like about this extension is that I don't have to navigate to twitter page repeatedly, not even have to login! Just as and when I want to see tweets I click at this extension.
Here is the default view:
Tweets containing 'Viracct' now appear under Viracct tab:
