Press to preview
Hold a button and the dispatch board plays what it will do; let go early and everything springs back.
It’s 8:40 on a flooded morning and three jobs sit behind closed roads. Every button under this board changes somebody’s day, so none of them acts on a click.
Press and hold “Reassign Okafor’s jobs.” His two jobs leave his lane and slide into Brandt’s, and the totals roll to the numbers you’d end up with. Let go before the ring closes and it all springs back. Hold until it closes and the change sticks, with Undo in the same spot. From the keyboard, hold Space and press Escape to back out.
A confirmation dialog asks the same question, but it covers the board while it asks. Here the preview is the question.
The hold costs just under a second and a half. For the operators I had in mind, I’d keep it on actions like these, which cancel or move a customer’s appointment, and leave everyday actions as plain clicks.
