manual changes to TOC aren't saved
NCBI reported this in #103 (closed). I have tested and get the same behaviour.
- Current behaviour: User manually reorders the TOC parts, previews and is happy with order, does something else [in the same book or another book], goes back to that book, the parts are reordered from what was manually ordered and previewed.
- Expected behaviour: User manually reorders the TOC parts, this order does not change unless user manually reorders.
