[Z7] Draw cannot be undone by ctrl+z

I hope lines of draw can be undo and redo by keyboard shortcuts. I also hope that the eraser can be set to erase by lines.

Do you know any other software that does "erase by lines"?

I searched again and found its name may be object eraser_(:з)∠)_ The eraser of Jnotes can set to object eraser instead of pixel eraser so it can erase the whole line when my pen touch it.
