Possibility to change hdri (it's free on hdri haven :) ) and change light rotation
This one is already in my bucket list :D

This already works on the Linux version because chrome uses OS-specific color pickers. I'm working on adding a color picker that will make this work across all platforms.

Not quite sure what this means tbh
Also try to add things that do not exist in substance dessigner to be able to create competition and differentiate your sofware
In time it will. I just gotta hit the basics first.
