Notability has the feature of partial erase that erase by pixel rather than in blocks as GoodNotes has. This is important to people who draw their notes and make cartoons or diagrams.

In GoodNotes, the eraser sizes are limited to three, and the smallest is way too large while the largest is too small.

In GoodNotes, if I am erasing partially, the stroke is erased block by block and this prevents accurate erasure. It should work as accurately as the pens do.
