Knolling is the term for arranging your stuff in rows and columns.

The word ‘knolling’, which literally means organizing objects at right angles, was first used in 1987 by Andrew Kromelow, a janitor at Frank Gehry’s furniture fabrication shop. Kromelow used to arrange his displaced tools at right angles on all surfaces, and called this routine knolling, because the tools were arranged in right angles — similar to Knoll furniture.
