Download and execute the msi setup program. Setup detects the location of your
My Documents folder and installs the addin to My Documents\Visual Studio 2008\Addins and
My Documents\Visual Studio 2010\Addins. Restart Visual Studio 2008/2010 in order to load the new addin.
By default the addin will ensure no more than 10 editors are open at a time. You can configure the number of editors that can be open at a time by going to
Tools -> Options and then Text Editor -> Auto Close.
Each time you open an editor in Visual Studio the addin will check to see if the maximum number of open editor windows has been exceeded. If it has then the addin will close the least recently used editors until the number open is equal to the maximum. Visual
Studio will prompt you to save changes to the editor that is closing if necessary.
