A lot of topics getting mixed in here.
On the license question, Newfangled did not attach a specific license to the wizards. There is a code protection scheme with a password, but its not to hard to get around. Obviously we would be greatly upset if someone took the code and tried to sell a modified version. But if a user figures out how to modify it for his own use there really is no restriction.
My worry is that modified version will get out and make support impossible, Its hard enough when there are old versions around, but trying to support code that has been modified by a user is impossible.
There are countless ways to restructure screens and wizard like functions. I have started a lathe set that has screens for manual mode, running programs, facing, boring, tapering, etc. These are a bit like power feed screens where they do the operation when you push the button, not generate Gcode for later use.
My lathe screens are not finished, and I just sold my lathe so it will be a while before i have another lathe running and can get back to work on the screens.
I had along talk with Brian last night about screen issues. There are some problems with the way it currently works- seen by the long time it can take to paint screens when you load wizards or screens. He has some fixes in mind that may get into Mach V4. That would make much quicker to switch screens and make a many page set possible.
Back to the original question, Im not sure I understand what you want by a single hole drilling. Do you mean you want the wizard to make stops at each location, like a 2D machine would? Because of the complexity of getting into and out of the wizard a choice for a single hole seems more trouble than its worth.
