Hi Calvin,

Does that not mean you could use svg symbols for this?
I know parts of svg is made dynamic, as you can define the color of svg's.
I'm not sure if you can make other parts of an svg dynamic too?
Would be cool to be able to use expressions for example to
color/rotate/size svg symbols?

Another thing I was thinking about: did you explore the geometry
generator stuff?
