Hi Mike,
Thanks for the kind words. I am glad you like CabWriter and hope we can develop it to the point that you are ready to use it in your work. Revision 1.0 will come out in the next month or so. Unfortunately, it will not have dado support. However, dado support will be the first thing we add to Revision 2.0 and I expect it will follow Revision 1.0 within six months.

Sliding dovetails, which I use for furniture making in my own shop, is not something Greg or I have talked about. But it intrigues me. Is it as simple as two vectors at equal and opposite angles? I’ll talk to Greg about it. Thanks for the suggestion.
