Locking a shift
Right-click any assigned shift and choose Lock shift, or click its padlock. A locked shift is never moved or replaced by the solver, regardless of how many times you solve.
Dragging shifts
You can drag any shift chip to a different staff member on the same day. If that person is not normally available that day, the editor asks you to confirm first.
Editing shift times
Right-click a shift and choose Edit shift to change the start and end times for that specific assignment without affecting the underlying template. The assignment is automatically locked when you change the times.
Removing a shift
Right-click a shift and choose Remove shift to delete that assignment. If the shift came from a requirement, an unassigned chip reappears in the Open shifts row.
