single schedule that includes classes with different period durations.

I suggest having the final printable format as an Excel file. This would make it easier to adjust the final layout and to add the school's logo.
I also recommend allowing sorting of teachers by cycles or groups, as well as sorting classes — it makes it easier to navigate, especially when creating schedules for French schools.
One more suggestion, if possible: it would be helpful to generate a single schedule that includes classes with different period durations.
Thank you!

If you have different time periods, then you must set smaller FET hours. For example if class A have got 45 minutes and class B 30 minutes, then you need to set a FET hour as 15 minutes. So class A get 3 FET hours and class B get 2 FET hours.
