Currently different transaction types show different details. Asset transactions don't show "To" and "From". On RVN Transactions the "From" is almost always listed as "unknown". Maybe change this to list a sending address and if there is a label on one of the sending addresses, put the label after it in parenthesis like it has handled in the "To" section. See inconsistencies below:

How easy would it be to change the library to have versions of the encode and decode functions where the payload JSON was provided / returned just as the JSON text?

There are other good JSON generation / parsing libraries available, and some people may wish to use them to generate or process the payload, rather than the built in claim processing.
