I would love a notebook that focuses on the mechanics of typing first, and is then supported with handwriting. An example would be a typed manuscript that can be marked up with handwritten edits which alter the text.

I want to write a few paragraphs, and then use a pen to Scribble out (delete), circle and draw an arrow/drag (rearrange), highlight/underline, or add text. It would be as though my red pen was magic and made arrow keys (or even VIM gestures) feel slow

This notebook template closely replicates the writing experience of iA writer ( A centered text column, with a typewriter mode, but is also supported by the gestural handwriting features of GoodNotes.
