Notes in the outline that are automatically filled with the highlight content do not reproduce the line breaks in the pdf. As a result, many times they are unreadeable. Furthermore, supporting line breaks would make them readable when exported as rtf to DEVONthink.

I attach a sample pdf original. This is how its highlighting is rendered unreadable now:

"We might imagine quickly sketching out some writing cues on index cards, each representing a short vignete: the gren-haired girl the penny whistle table a talkative bookseller the old man who saves us fom the pickpocket honey cakes juggling knives and torches the gun and Bible dealer police, clubbing a thief to the ground a seller of colorful prayer papers"

This is how line breaks would make it readable:
