If those are the most serious problems you can see then I think we're in
good shape. I will incorporate your comments as best I can. However, I do
not guarantee to do precisely what you wish in every instance, and I rather
object to the peremptory and didactic tone of some of your observations
(particularly 3 & 4), with which I do not wholly agree, and where
alternative views are tenable.
