+1 I've been practicing with printing from Affinity to my laser device as well (I'll be happy to rid myself of Illustrator). While very-small-stroke widths work, they are cumbersome when someone wants their logo at two very different sizes, where a stroke my switch from too-small-for-the-laser to large-enough-to-vector with resizing. It simplifies my workflow to have the ability to pin the stroke as hairline. Would it be possible perhaps to make hairline as toggle-able value, separate from the numeric thicknesses? Would that make implementation more complicated or easier? Cheers! Been enjoying using Designer the last month or so!
