Hi @Stepo Kedur,
Thank you very much for the suggestion!
Considering this is such an important part of texturing, I'd also love to see UV Unwrapping inside Substance 3D Painter!
We are frequently discussing about import & export inside Substance 3D Painter to simplify the workflow. The automatic Unwrapping feature was a part of this and to be honest, we're currently looking more for automatic solutions, than manual solutions.
Regards,
