The first thing that came to mind was my friend's project to do a SVG editor in Godot Engine https://www.godsvg.com/.

I'll write my first impressions of https://github.com/hyvectorapp so it helps usability and improvement.

Oh it's a freemium app.

hyvectorapp starts off looking like figma, penpot style which is a good sign.

I can export svg [x]

There's no align to grid system.

vector tracing is not generally solved except via the vectormagic product and machine learning research prototypes. I wonder how you solved it.

Can't interact more today so I'll end with this note of hopefulness.
