Hi @martinkoss ,
New Sync Tech. is on the way.
Thanks @DrJJWMac to point out our world view. The documents, no matter it’s PDF or Epub, are just a basic material for MarginNote. MN3 created a new expanding note space for the traditional book which you referred to as PDF. MarginNote nearly does nothing with PDF. Just use it to create notes in MarginNote Database, which we called excerpts. These excerpts do not save on PDF format. Everything you do like annotation, highlights, or something else is all in the database, which originally exports as marginpkg notebook files format.
If you want PDF export, it means to transform the notebook database into PDF. That’s why you got pretty big files and wait so long a time to do so. Our transforming engine is working within that waiting time.
I hope this could help you understand MN’s world view.
Lanco
