In this TechEd 2010 video, Patric McElroy demos some new and future SQL Azure capabilities. It's worth watching the entire 80 minute video but if you only have 6 or 7 minutes then the piece you won't want to miss is Project "Houston," a new Silverlight based management tool for SQL Azure which my team has been working on for about a year. It targets developers who're using SQL Azure as a backend repository for their web apps. It'll be hosted on Azure which means as an end user you won't have anything to install on your local machine. It starts at ~51:00.
