Upgrade Design Toolkit

An internal Figma plugin for the Upgrade design team, published to the organisation and improved over several releases up to version 5.0. It brings the most repetitive jobs into one place: Case Master for sentence case, a Monthly Payment calculator, a Design Auditor and Mimic Style.

I tracked where my own time went on a typical project. Much of it went on small, repeated jobs: fixing title case across a file, working out financing figures for every price in a mock-up, and checking consistency by eye.

Each job was small, but together they slowed every project. And a wrong payment figure in a fintech mock-up is a compliance risk, not just a typo.

• One plugin and one design language for every chore
• Accurate financing maths without a spreadsheet
• Safe bulk edits, with exclusions and undo

1. Fix one chore first

   It started as a standalone pricing calculator using the standard loan payment formula, applied straight to selected text layers. That became the pattern for the rest.

2. One shell for everything

   Each new chore became a tile on one home screen, with the same header, scope controls and status messages.

3. Protect the legal copy

   Case Master skips disclosure and legal frames, and keeps a list of words that are never lowercased.

• One plugin instead of many: designers remember one shortcut, and every tool feels the same.
• Legal and disclosure frames are skipped by default, because a careless bulk edit is worse than no tool at all.

• Daily chores went from many manual steps to one click each
• Payment figures in mock-ups come from one tested formula instead of ad-hoc maths
• Published and adopted as the team's shared toolkit, with regular releases

Internal tools work when they disappear into the routine. Consistency between tools mattered more than any single feature.
