Is there any Visual Studio 2010 add-in that will automatically group cpp files and headers in different tabs, and possibly also automatically open / close the corresponding cpp / header files when opening a specific file?
This add-on is similar to providing the first function you wanted, although I don’t know if it works with h / cpp files: http://visualstudiogallery.msdn.microsoft.com/EBF6137E-AA2D-4DC9-860A-F04168F11CD7 .
Oh second, I'm not sure what you really always want. I think that most of the time, this can actually annoy you, as you finish closing files that you never had to look at.
