User interface design is often called upon to make up for human failings. We
get distracted, we forget, we have trouble breaking bad habits, we easily
acquire new ones. This is true no matter how much training we have. The
designer tries to take such issues into account up front, but sometimes we find
out later and make adjustments.
My cognitive science professor, Don Norman, put a heavy emphasis on embedding
knowledge "in the world." Signs and indicators need to be as unambiguous as
possible to help those of us who can't or won't pay attention. Ideally the
indications are intuitive, so users adapt to them easily and don't feel
oppressed by them. That distinction is in play here. And while I'd love to add
a dozen more LEDs, a klaxon horn, and a Van de Graf generator to the K3's user
interface, we have to work within the limits of the existing hardware.
Providing an optional means of reinforcing split/non-split state is in the
tradition of design iteration -- using feedback about real errors that people
make, then minimizing them. That's why we're having this conversation.
