Suggestion Puntuado con 4 de 5 estrellas

This is a really promising extension.
I have a suggestion: when creating a new booklet, automatically add pane number 1.

Esta valoración es de una versión anterior del complemento (0.3.5). 

Thank you! And very good point; all new booklets created come with an initial 2-column spread (added in 0.4.0).
