If you intend to try to sync event dates and such, that data will probably remain.
Hi Craig, Yes, I wanted to try to tame my convoluted timeline by syncing everything. I have used Scrivener for a few years and am one of those who has never had a technical issue with it (knocking on wood as I type this), but I do frequent the Scrivener forums and see all manner of crazy issues that people have. I'd just hate for my demo to do something to break Scrivener.
The demo won't break Scrivener. Most (if not all) of the links between Timeline and Scrivener are accomplished via custom metadata fields, and you can always delete them from within Scrivener if you feel you must.
