Your dashboard is yours. The cards on it, and the order they appear in, are a personal setting — changing them affects nobody else.
Choosing your cards
In Dashboard Settings, switch on the cards you want and off the ones you do not. Fewer, better cards beat a wall of numbers nobody reads — start with what you would act on before lunch.
Putting them in order
Drag the cards into the order you want. The one you look at first belongs at the top — for most people that is what is due today, not a chart.
Desktop alerts
Turn on desktop alerts to be notified while you are working in another tab, with an optional sound. Your browser asks for permission the first time; if you refuse it, alerts stay silent until you allow notifications for the site in your browser settings.
A CARD IS USED IN MORE THAN ONE PLACE
Some cards tell you what else uses them. Switching a card off only removes it from your dashboard — it does not affect the reporting behind it, or anybody else's view.
