Drag-to-book time picker

What it does

• The window is as long as the job, so people see how long they'll be without their car.
• Booked time pushes back with a soft rubber-band feel. Pull past the middle and it hops over.
• Changing the service resizes the window with a spring and finds the nearest gap that fits.
• Page week by week, open a month view to book up to six months out, or jump to the earliest day the job fits.
• Days with no gap long enough grey out, and each day shows a tiny map of its bookings. Sundays and holidays show as closed.
• Hover previews where a click will land. Arrow keys move it, Shift moves an hour.
