this is a fine product
i will use it joyfully and gratefully.
i like it that it was loaded up with extras, like the charts and chapter K.
i look forward to chapter P.
so far, i have only found one thing i would have done just for asthetics and consistency.
it concerns the links that are in red. some of the links are bracketed with black like this ( )
some are like this first black and then red, some are red and red.
its a small criticism, over all i am excited to have it.
