Does anyone have experience migrating/exporting from Notabene Ibidem? If so, do you have any suggestions as to how I might proceed? What is the best export format? And how do I even do it, given that I can't find an export function in the Notabene menu?

I have a vast bibliography with hundreds of entries, a few fields I created, and certain amount of notes. I also have some entries in Greek and Hebrew alphabets.

Thank you!
