Hi there,
1) In LiquidText, you have the ability to create links not only between different pages of the same book but across different books in the app. I want GoodNotes to implement it in pdf textbooks and digital handwriting notes and it will make study and research very easy.
2) In LiquidText again there is a feature in which you pinch to collapse the pages so that you could compare the material between two different pages of the same book. It’s awesome and it will make studies very easy and productive. So please work on it
3) Please either add the capability to extend the margins on all four sides of the pages of a pdf textbooks for digital handwriting commentary or add sticky notes where we could just digital handwrite our notes and tap to minimize or maximize it. Key: we must have the ability to handwrite our notes in these sticky notes.

ALL 3 will make GoodNotes 5 a default pdf annotating and notes app if implemented in near future. Hopefully you’ll work on them.

Regards
