We have been designing and using computer software since 1972.  One of the biggest problems in designing software and the User interface is the "tipping point of usability".  The tipping point occurs about 30 minutes after you learn how to use the program.  The tipping point represents the point in which you are no longer a beginner but an experienced user.  The point in which the beginner stuff to guide you through a process now is no longer relevant and usually gets in the way. The extra time consuming stuff that is only important when you do not know what to de next.
