Visual Studio 2010 Extension for grouping files into folders

I'm looking for a开发者_JAVA百科n Extension that allows me to group Files into Virtual folders.

Example:

I have a Solution with 3 Projects. UI (MVC), Security Layer, BusinessLayer/DAL.

Each of the 3 Projects have some classes/views that handles stuff for let's say "User Management":

• UI : Views, Controller, ViewModels
• Security Layer: Security Checks
• BL/DAL: Business Logic, Data Access

What I want is an Extension like a "Logical Solution Explorer" where I can create Virtual Folders in it and put links to all "User Management" classes/views in it.

Is there something like that available?

I really like the Favorite Documents extension. It sounds like it could help. You can find more information about it at: http://www.svprogramming.net/favorite-documents/
