We have two gesture options, squeeze and double tap. I would love to be able to set squeeze to bring up/put away the eraser and double tap to switch between my two most recent tools, but ignore the eraser as an option. That way i can go back and forth between my pen a highlighter without having the erase override one. Example: highlight something, double tap to write with the pen, squeeze to erase a mistake, squeeze to return to pen, double tap to go to highlighter.The highlighter/pen sequence could be totally separate from the eraser function.
