Because I don’t use Scrivener, I wrote myself a macro for LibreOffice that extracts various synopses and reports from the CSV export file of Aeon Timeline 3 and creates ODT text files from them.
It uses part of the data structure given in Aeon’s “Novel” template. The narrative numbering scheme has to be set to “Outline Style”.
For general use, I have made an extension for LibreOffice 7. It is open source and free, but still in the experimental stage, so users should check for updates from time to time.
At the moment I am still trying to understand the native .aeon file format so that in a later version the intermediate step of CSV export can be omitted.
If you want to try it out, you can download the extension from my project homepage.
