I am a simple man. All I ever wanted was drag and drop for source control. That folder chooser dialog was a bear. Now we will get it with Visual Studio 2008 SP1. Thank goodness. From the web site:

• Simplified the user experience through cleaner "Add to Source Control" dialogs, drag and drop support to the Source Control Explorer and a much easier to use "Workspace" dialog for working folder mappings.
• Version control now automatically supports non-solution controlled files.
• Various changes to the Source Control Explorer such as a new checkin date/time display column, local path hyperlink support and en editable source location field.

I am not a big fan of installing a beta SP on may dev laptop, but I gotta tell ya, I did it for that feature alone.
