I've been on Itch ever since I first joined the platform but I don't usually comment on things here.
So far this seems to be pretty good! Feels like I'm right at home as for simple SDF modeling since I've been using MagicaCSG for quite some time in the past before the dev scrapped its fully-functional free license (which left me wondering why there hasn't been any updates past 0.0.2).
I know you might've already had this planned, but would you consider being able to insert reference images into the viewport? I've seen Blender, Plasticity, and MagicaCSG have this feature and I'm wondering if this would also be possible—obviously not now.
