Right now it is not possible to snap a point to just any spot on a surface, you can only snap to edge curves of surfaces.

I'd like to add something for this in the future but it probably won't be very soon though.

This is coming for the next beta, there will be a "Make copies" option for rotate and scale, and you'll also be able to make copies by holding down the control key when clicking in rotate, or by doing control + drag.

For move you can actually do multiple copies right now by using the "Copy" command that is right next to move.

Thanks for giving MoI some publicity, I really appreciate it!
