To keep Basecamp from getting lost in all of your Firefox or Safari tabs, you can create a Basecamp icon on the menu bar on your Mac. That way, you can launch it just like any other program, without first having to launch your web browser. Simon Dorfman explains how.
You can also use this approach to create stand alone menu bar icons for other sites that you use a lot, such as Gmail or your blog admin page.
