Hello! I've noticed a bug (I guess it is one, right?) with regards to the table of contents: when writing with no bookpart block, the pdf bookmarks are exported to file correctly. They appear in any PDF viewer. However, the same doesn't happen while using the bookpart block: everything works normal except for the absence of PDF bookmarks.
