I ended up creating rough drawings on a jpg I placed a 20x20 grid on to work out what I wanted and act as my blue print before I laid down the first land mass. The grid acted as a coordinate transfer to keep me on track and by creating jpgs for awhile when I changed my mind on something. I had less major changes while using the editor, and most mistakes were minor inside of say 8x8 miles. It's old school brute force but, I learned how to use the editor in more depth than I really think I wanted to. 2000 miles of mountain range and 2000miles of fjords. As soon as you can, get yourself a raw file elevation editor to do the grunt work.
