I use variables for everything now. I use the apply variable functionality A LOT. Digging down in the font-size picker, font-picker, font weight picker just gets so annoying and really interrupts my workflow. I really how you did it for line height and letter spacing. Would be nice to just have an apply variable functionality work the same way for all the parameters. I am praying to the Figma gods this will be improved soon.
Thanks! ❤️
