This is an amazing piece of software and I appreciate all the work that has gone into it. Here are few suggestions that would make my work easier.
A tool isometric view button would be really useful.
In the tool library, storing the maximum ramp angle of a tool would simplify things for most operations.
In 2D bore add an option to bore from Bottom to top (this can be done with a thread milling cycle but is not ideal)
In the face function add in a spiral facing option. (side note, why does the face function always use a square or rectangular bounding box even when round stock is selected in the setup?)
In the drill cycle the bore milling function does not pick up a diameter off the selected face or hole which is kind of weird. In the same function it asks for a Pitch as in thread milling it would be more useful to ask for a ramp angle.
