One of the most frustrating experiences for designers and developers is how much time is spent keeping code in sync with current designs. InVision Design System Manager (DSM) attempts to solve this problem by putting the power of design tokens in the hands of designers and developers. Design tokens act as variables that store your styles so that your colour, text, and other style attributes will always be up-to-date. To put DSM’s design tokens to the test, Martin (developer) and I (designer) designed and built two prototype web apps of our favourite to-do list framework, One Big Thing.
