@jackie_w - excellent, glad to hear it is working well for you. After all the false starts with my silly errors in earlier betas I think it is finally at the stage it should be.
As for the file naming, yeah my compromise was "I'll think about it"
. You ask why anyone would care - I tried that argument once before on this thread and he who shall not be named stated otherwise
. I really want to get this officially released and given my recent track record of breaking things I certainly don't intend to change it for the 1.2.0 release.
I am however very interested if JSWolf (or anyone else) has found an inline TOC that didn't update correctly, since my only experiences have matched what you have said of it all working fine. Certainly if the book had a broken inline TOC before conversion this plugin isn't going to magically fix it. But until I see it in its original state for myself I don't know for sure whether there is a bug in there or not.
