Once again, it took me about an hour while watching my shows to get a custom one made.
The first version operated by me downloading the pages one by one to a directory, the Python app parsed the html, downloaded the files and renamed according to thread name.
After a few iterations the tool just grabs a cookies.txt file exported from Firefox and can take any thread URL, browse through it, skipping existing files and determining if everything is already downloaded
I could easily have it just watch a set of threads for new content and download automatically, but the current system is fine =)
