If you work on bigger projects with a large amount of source files, you might want to be able to store files as a group of favourites and to re-open them all at once later?
The free plugin Favourite Documents makes it possible!
Favourite Documents is a bit like the Document Session Manager many people have used in Visual Studio 2008, but for Visual Studio 2010, that Add-In does not work anymore.
Just download the .vsix file, double-click on it to install, and enjoy!
