Some add-ons for IE7 that are worth getting:
Bloglines Browser Plug-In: The Bloglines Browser Plug-In will enable you to use the Bloglines RSS aggregator from your browser and subscribe to RSS feeds with one click. The plug-in will be integrated into the RSS Aggregator functionality of your IE7 browser bar and will be accessible through the RSS Aggregator button in your IE7 browser bar. Note: you will need to register with http://www.bloglines.com to use this plug-in.
del.icio.us Buttons for Internet Explorer: Integrate del.icio.us right into Internet Explorer with this del.icio.us extension.
Inline Search: An extremely useful free add-on for Internet Explorer that mimics Firefox’s search behavior. It turns searching in a web page into a non modal research experience coupled with a find as you type facility. It integrates flawlessly into IE (version 5.5 or above), giving it that little extra that makes you a lot more efficient when you are looking for a specific piece of information.
IESpell: IESpell is a free Internet Explorer browser extension that spell-checks text-input boxes on a Web page. It should come in particularly handy for users who do a lot of Web-based text entry (Web mail, forums, blogs, diaries). Even if your Web application already includes spell-checking functionality, this utility is faster than a server-side solution. Plus, you get to store and use your personal word list across all your applications instead of having to maintain separate ones on each application. The program installs as a new button in the IE toolbar (and as a new menu item under Tools). After filling in a form, click the IESpell button and it pops up a dialog similar to the Microsoft Word spelling checker. In version 2.1.1 build 325, ShowModalDialog can take any HTML elements, and support for ignoring words marked with an underscore has been added.
