I've always been a sucker for the details - and unfortunately line height and letter spacing are very commonly overlooked, even in otherwise solid designs. The truth is that fonts cannot have the same spacing values at different sizes, and the default settings are more of a sensible starting point. I noticed that even with all the plugins on Figma community the only way to adjust your type scale's spacing was to do it manually - so I set out to fix that problem. I spent about an hour brainstorming the features, outlining the formulas for the spacing calculations and putting together a small essay of a prompt - and I got a simple prototype working thanks to ChatGPT, as a sort of MVP. Later I went in and manually refactored most of the code Gemini code assist, and redesigned the UI. I hope you enjoy using my plugin!
