I think I’ve answered my own question. It would seem that the edit tool adds nodes, not the pen tool. Seems counter intuitive, but I’m glad it’s at least possible

This seems like a no-brainer, but I’m not having any luck. If I make a curve using the pen tool, I can’t find a way to go back and add a point anywhere along that curve. Tapping on the curve with the pen tool either creates a new curve or continues adding points from the end of the curve. Is there a way to add a point to a curve like I can in illustrator?

Is there a way to quickly switch to the eraser tool other than tapping it in the toolbar? For example, in Procreate, I can set it so that my finger always erases, and the Apple Pencil uses the currently tool.
