With Visual Studio 2008 shipped and the first service pack likely coming in the next few months, it's time to start looking forward to the next version of Visual Studio and .NET. I've started a list of some of the things I'd really like to see included in the next release, and I have some people adding their own ideas to the list as well. At the moment, the list includes:

• Support for generics in ASPX markup
• Save/Retrieve Visual Studio settings online (ideally in a Microsoft hosted cloud service)
• Recursive FindControl
• Remove Title="Untitled Document" as the default for new pages
• Automatically add runat="server" to any asp: control in source view in Visual Studio
• Better support for virtual path provider-based projects

Check out the complete list and discussion, and add your own wish list items, here.
