That´s the problem tho, from a computer's point of view you have not read this yet.
you just read another chapter with almost identical content.
to make a feture with the effect that you want they would have to redesign the whole system, it's not just something you can slap on as an addon all willy nilly.
That said, it's not like its impossible without a redesign...
you could for example make a script for ignoring chapters with the same name, but then you would have to have a more streamlined way of naming chapters or something similar.
