This would be a killer feature, especially now that Amazon's entered the e-notebook space with the Scribe. Given GN's spectacular PDF tools, I know it could do great things being able to mark up ebooks.

Absolutely need this. There’s no way to easily mark up a book like you can with a physical copy these days!

Please add. No other ebook reader would be able to compare

Im also suggesting for the ability to import and edit .epub file !

Yes! Killer feature. Imagine being able to mark up books with my Apple Pencil in the way I want!

Please add this feature.

SUCH A NEEDED FEATURE! WOULD KILL ALL OTHER BOOK READERS IF DOABLE

+1

Please add..its been a feature everybody is asking for many years now!

same here. This is indispensable for working with technical literature.

Yes please! I feel out-of-luck if I can't find an eBook in PDF format, because I only want to use GoodNotes for reading/marking-up my eBooks. Please add this.

I am dessperatly searching für a epub compatible tool. Would be awesome to use it as a goodnotes feature in the future.

yeah this will be very helpful. I'm a student and sometimes the e-books I get only have epub file

This would be awesome!

I need this

+1 !

Please add an epub feature!

This function would be so helpful!

This would be a game changer for me. I would also pay for this ability.

Please add a feature to import ePub for editing
