I have put a snapshot, preparing a new official version.
New constraints for Mornings-Afternoons mode users:
Following the suggestion by ghani1990: I added teacher(s) max gaps per morning+afternoon. Please test on your file, and also in combination with no gaps per afternoon and max gaps per day/week for teacher(s).
Following the suggestion by bachiri401: I added students set/teacher(s) begin mornings early max beginnings at second hour. Please test on your file, and also in combination with: students early, afternoons early; min hours daily/morning, max 0 gaps per afternoon for teacher(s), min mornings/afternoons per week.
I hope to release the official 6.1.3 in a few days.

I added a new snapshot, in the Mornings-Afternoons mode the time constraints for teachers and students are better organized (suggested by bachiri401, Benahmed Abdelkrim, and Khineche Kaddour).

I added a new snapshot, the activities time constraints menu is better organized.
Also, in Mornings-Afternoons mode, if you use the constraints of type mornings early+afternoons early, I made a theoretical improvement.
