Here is an example of a RemNote document i exported for Adobe Acrobat, and as you can see only the cloze symbol (?) is editable. I have to manually edit the PDF and I come up errors with character recognition.
Back in 1.4.7 we can Export the file into Acrobat PDF and it will be a searchable PDF.
Edit: Clozes and the ‘previous’ and ‘next’ bottoms at the top of the PDF were only rendered by RemNote. The rest of the document are not directly editable/searchable.
Images also appear to be enlarged by themselves compared to 1.4.7.
