Allowing people to sign in red, blue or black ink.
Idea is simple. Allowing one to sign in red, blue or black ink. I bring this idea because each color of a pen legally identifies a person if your dealing with law.
Red ink - living, flesh, human being, creditor.
Blue ink - Debtor
Black ink - Corporation, entity
It's a small feature but it will be beneficial in the long run when you are dealing with those who know legality.
