Rooms as columns, a vertical time axis, collapsible hours. Like a sheet, without the manual formatting.

Grab a box by its header and move it to another room or time. Time snaps to 5 minutes, the duration stays.

Type names freely and drag them into groups. One person can land in several boxes.

Yellow stickies for maintenance breaks or remarks - no students or teacher, excluded from clash detection.

Copy a group with its students and paste it onto another day. Monday -> Friday in seconds.

A history of recent actions and Ctrl+Z. You delete without prompts - undo is the safety net.

One plan for the whole school. Colleagues' changes appear automatically every 3 seconds.

The draft turns into groups and lessons - in one transaction, skipping holidays and creating student accounts.

A room added here shows up in Settings. The front desk manages rooms without access to the rest of the locations.
