Online booking: reorder your services by dragging them
In Online booking, grab a service by its handle and drag it where you want: your booking form follows this order. So do the categories: the one of your first service is shown first.

How it works
Where: Online booking › Services, the handle on the left of each row. With the keyboard: Space to pick it up, then the arrow keys.
The "…" menu of a service also offers "Move to top", "Move up" and "Move down".
Example: mostly CarPlay and coding work? Put those services first, and the Equipment and Diagnostics categories come before remapping.
