Hi Johncs. Love your tool. I think it would help map makers if you added the ability for us to use arrow keys to pan around instead of exclusively relying on the pan tool and dragging with the mouse. Also, maybe the edge tool could draw diagnol lines as well?
Diagonal lines probably won’t ever be added to Shmeppy. Panning with the arrow keys sounds reasonable though, I can try that out and see how that feels.
