It would be nice to be able to adjust the sensitivity of scribble to erase. Sometimes, when trying to erase large blocks of writing, if you don't scribble thoroughly enough Goodnotes won't recognize that you're trying to erase and you have to do it again. Maybe there could be a feature for us to determine how sensitive we want it to pick up on scribble-to-erase, for users who use it really often to erase?
