I tried a flow based tool for the Mac in late '80s. It really didn't make things easier - and it had terrible support for things that text languages take for granted, like foreign library import. Computer scientists have not "hidden away" the idea. It simply hasn't provided close to the value that text based languages have in real life. The new tool is as much snake oil as any tool before it that uses the same language in its advertising.
