very nice and simple to use out of all SDF modelers i tried this is fav. One thing i have to complain but really more of a observation actually is that when you grope shapes and if you want to scale the group in only one axes you can't.

Thanks a lot for the kind words, glad you’re enjoying it!
You’re absolutely right about non-uniform scaling on groups — that’s not supported at the moment because of how the system handles transformations internally. Once you mix non-uniform scaling with rotations in the hierarchy, the math turns into shears and other distortions, and the current SDF pipeline isn’t set up to handle that cleanly.
It’s definitely a technical limitation rather than an oversight. Appreciate you pointing it out, and who knows — maybe one day I’ll find a neat way around it.
Cheers,
