I think those are very good comments and I agree. Andy came up with the idea for the accuracy curve and being able to input from a CSV file is major plus.
Again, thanks to Andy, we have added digital pen support for the Map Editor (this will be the next module released for beta-test). Perhaps it can be added for drawing the Accuracy curve. However, a lot of people don't have digital pens (in fact I had to borrow one from an artist friend just for testing).
