> Toasts also give you a good place to put other shortcuts like “Item updated. [View item]” that make it much easier to act on state changes Not if they go away, and take their “[View item]” button with them, before you've had time to read the notification, decide if you want to click the button, and actually get your cursor there to click it.

Maybe your browser should could have an icon for same instead making it more standardized across different sites.
