Today’s task involved converting an SVG diagram from light mode to dark mode manually to make it presentable for the “big boss.” This was done in a bit of a rush, so there was no time to do something sophisticated like modify the SVG file directly. I just did it in Affinity.
Somewhat related: the SVG exports from TLDraw are a little strange. Each object has a separate outline and fill construct, or at least the boxes and text-boxes do, or at least that’s how they’re presented in Affinity.
