wrt to IDE auto-completion: when you write by hand you don't actually write correct programs. You make assumptions about what level of detail you want: the mundane and boiler-plate parts can be ignored, or reduced to a descriptive function name (e.g. GET-INPUT) then the interesting parts can be fleshed out to any sufficient detail. Usually as I progress through a project, my later "models" of it are smaller, as I have understood all the components piecemeal. I tend to draw a few squares when I fully understand a problem, otherwise it's a long rambling into emacs' org-mode.
