that behaves.
Move lessons directly. See conflicts before they land. Keep the entire school in one coherent field.
Local-first Constraint-aware
Your timetable stays in this browser unless you choose a cloud solve.

Chronexa keeps the reason beside the move. Teacher availability, occupied rooms, class collisions, and fixed lessons remain visible while you work.

The card follows your pointer directly and commits in one motion.
Watch one conflict become a valid week.
No file required. The miniature school below runs the same placement story in a smaller frame.
