What it says, among everything else, is this: "a fourth touch in a single vertical column, or that forms a fourth corner of a rectangle, gets ignored".
Is this correct, first of all? If yes, is it possible to change that in settings?
I am more interested in four touches in a column than in the square corners. If you wonder why, one of the tunings I am using on guitar requires that quite often.
