From the developer:
SmartActivate is a scripting addition that helps you activate a specified process with bringing only one window into the frontmost. Normal activation processes bring all windows belonging to the application into frontmost. But in most case, only one window is required. SmartActivate allows avoiding the crowded screen when converted by needless windows.
