I don't think he meant "difficult" when he said "confusing." I took that as "a great deal of potential for error" rather than "difficult to come up with a way to implement." Also, consider that English is not Report's first language. The technical details are there, but Report would need to set aside time to parse it all first. He has already put Texmaster on indefinite hold once due to lack of sufficient free time, so I get the impression that -- although he is working on it again -- he has less time to devote to it.
