Also on the topic of gaps... liminal space IS precious. It doesn't require coding per se though. You can problem solve, jolt down a solution THEN only implement it as code later on. What matters IMHO is that the potential solution is not lost, wherever you might be. For that... I have shower crayons. Point is, CAPTURE ideas, don't necessarily implement on the spot but of course if you want to, it's good to be able to.
