This girl is awesome. Everyday, she finds tips and tricks about the Visual Studio IDE and publishes them on her blog (http://blogs.msdn.com/saraford/default.aspx). Those tips can be delivered to your RSS aggregator every day.
She also has a book of many of those tips titled “Microsoft Visual Studio Tips – 251 ways to improve your productivity” (http://www.amazon.com/Microsoft®-Visual-Studio®-Tips-PRO-Developer/dp/0735626405/)
One of her latest (http://blogs.msdn.com/saraford/archive/2008/12/05/did-you-know-you-can-create-toolbar-buttons-to-quickly-toggle-your-favorite-vs-settings-371.aspx) would have been great before my presentation at DevTeach!
