Hi!
I noticed that when you have already drawn an arrow from square x to square y, drawing another arrow from square y to x cancels the existing arrow instead of creating simply an additional arrow-top at square x. I can imagine situations where a two-direction arrow might make sense, e.g. to indicate mutual tension. So I propose to allow two-direction arrows. Thanks for considering and for doing such amazing work!! Cheers Max
