2.4. Expedients and Experience

Is there any tool or feature that you feel is missing when writing software?

Guido: If I could sketch on a computer as easily as I can with pencil and paper, I might be making more sketches while doing the hard thinking about a design. I fear that I'll have to wait until the mouse is universally replaced by a pen (or your finger) that lets you draw on the screen. Personally, I feel terribly handicapped when using any kind of computerized drawing tool, even if I'm pretty good with pencil and paper—perhaps I inherited it from my father, who was an architect and was always making rough sketches, so I was always sketching as a teenager.
