Empty slots
This will allow teachers to view any classes throughout the year that we did not put lesson plans in. It will show all the "holes" that need to be filled with the lessons we did not type up in the class. There are some days we just do not get to planbook to put lessons in that we did that week or that day and we have to search and figure out what week that was.
Right now I am having to scroll and find weeks where I have holes in my weekly lesson plans. Having this idea would be great for me and a few other teachers I know who would like this suggestion.

You can view the empty slots via the List View for a class. Hope that helps, any questions just let us know!
