Hi, I already like very much GoodNotes as it is ! But here would be a really nice improvement : i would love to study several PDFs inside goodnotes. For this I would like to have on a half of the screen my pdf article I want to study, and on the other side a sheet of manuscript notes. On those notes, I want sometimes to just copy paste a theorem or a formula of the article (I am a mathematician). So it would be really great to be able to have :
1) split screen option
2) copy paste a part of the pdf as an image. I know that this feature already exists but for the moment we have to use lasso tool, the choose “copy as an image” option and then paste it on another page... I would find it easier to just move from one page (the pdf) to another (my notes) just with the gesture (like to copy from good notes to another app).

With those features, we would be able to do partially what Flexcil does for instance, or even partially what MarginNote does, more naturally than those app do. (I like and respect the features of those apps but like very much simplicity and something which is close to paper way).
Sorry for my English. I hope that this comment is enough clear.
Best.
