You can improve security of the booklet with secret splitting: type the strong part from the booklet then keep typing "hunter2" from memory. The (strong) booklet part protects from machines, the (weak) remembered part protects from humans. Weak passwords are ineffective only against machines, they are still effective against humans.
I suppose that typing "****" on the end of your passwords would work. Bit annoying to type out 7 asterisks every time though, maybe a word would be better?
