Add an eraser feature where we can choose if we will only erase or handwriting or just the highlighter

The eraser does noy allow deliting strokes made with the highligter.

It never mentions paying gives you a highlighter eraser although you would assume it's erasable. I think it should be as well but you can easily get around it by pressing undo...

True eraser doesn't partially erase highlights created with the highlighter tool. Add support for erasing highlights.

In a lot of scenarios, you can't erase highlighter stokes over pen stokes. I had the highlighter set to 8mm and the pen is set to 0.3mm I believe.

This should not be like this, since the highlighter stroke is much larger than the pen stroke and can be easily touched by the eraser without touching the underlying pen stroke.

True erase doesn't doesnt work on the highlighter!
