Most students and workers share notes and often do not use the same note-taking app. As you can only import notes taken in other apps in pdf form, you can't edit the handwriting: no eraser, no lasso tool etc... It would be INCREDIBLY beneficial if the handwriting recognition also worked with imported documents. I think applying the same handwriting recognition technology to imported notes with handwriting written in other note-taking apps would be doable. I really hope that you consider this idea because I believe that it will be a very crucial feature that will distinguish Goodnotes from the other apps. Also, it will be an incredibly great feature for students.
