Improve Save Functions of MFC Application

Our application has only a "Save As..." operation. Your task will be: (1) Add a "Save" operation (Control-S), reusing the existent "Save As.." code. (2) The "Save As..." is very inconvenient, because the dialog starts at the top of the filesystem, forcing the users to make a large number of clicks. The dialog should start at the current directory. Only experienced MFC programmers will be considered. MSVS-2010
