I would love to see the option to add Saturday and Sunday to the planner. I homeschool my children and sometimes we need to take a weekday off but plan to make up the missed work on the weekend. Since I also am using the lesson planner as a means of tracking our days worked, I can't simply bump the days for the missing day and keep it all within the same week so the following week aligns correctly. Since I understand most traditional schooling is done Monday through Friday, this would be unnecessary for the majority, but making a on/off toggle could resolve this.

I could also see this being very beneficial for tutors who also work with students over the weekends as well.
