At InVision I worked on making the sketch plugin behave more natively for MacOS, and become more visual. Designers working within a large design library could group their most frequently used or referenced components into custom sets for individual efficiency.
Additionally, I proposed we create and bundle useful design measurement tools with Design System Manager as part of an InVision toolkit. These included a contrast checking tool, type measurement, distance measurement and an advanced colour tool.
It was important that we accurately communicate the sync status of each item within your design system so you're aware that you are working with the most up to date library. For this, a sync indicator is included on every thumbnail showing components in sync, not synced and to be published.
