I have a design system that I use as a starting point to build up UIs for my clients.
My design library is based on atomic design and I benefit a lot from my systematic approach of using the same tokens across the whole library.
So the usual process for me is to decide what corner radius I will use to match my client’s style, decide on line weights for the borders etc.
Now it is a lot of work to override these values one by one for each component.
If I could create tokens and build units in Figma my job would be easier and quicker.
I imagine a similar process as to how you can maintain a type and color system.
(Also it is useful when my client asks for a change in these tokens. I could even quickly show them the difference between different options on the fly.)
