Hm yeah VS sometimes hides features
Some time ago i found out you can exclude source files from a build (show properties of a cpp file in the solution explorer, there you can exclude it). This stopped me from removing and adding source files just to stop them being compiled..
Instead of running two instances on the same debugger, it'll maybe better to start two vs.net instances and let each debug one instance (you can link the debugger dynamically to any instance, look into the debug menu).
Some more interesting features provides WholeTomatoe's VisualAssistX (http://www.visualassist.com/
). Some nice features I like there is of course the improved coloring and intellisense but also some buttons on it's toolbar, like switching between header file and implementation file of a class by one click
