Apples built-in drawing tools for the iPad

Is it possible to add apples built-in drawing tools for the iPad? Its nearly impossible to handwrite with the actual writing tool and the Apple Pencil.

I can only agree with that! That would be fantastic!

But if that doesn't work out, I would also be happy about a better handwriting tool and an eraser.
It would also be great if you could add images for Screenshots from TABS or similiar.
