Just installed the freshest 2.91 and tried boolean - oh, for me it looks and works amazing!
@AFWS & @Howard_Trickey Thank you very much for your work guys! It’s such a pleasure to work with blender! 
I have a question.
Is it possible in future patches to add snapping to the original shape (like it was before boolean) - for fast adjustment of position of the cutters?
When I have boolean modifier on the surface I can’t use snap to this surface on the both - cutter object or even his parent. Even if I turned off visibility of this modifier. I have to delete boolean modifier completely to adjust the position of any cutters and orient it to normal of the main object with snap to face. (oh, I hope you understand what I mean )
