Google is making your inbox more useful with vastly improved summary cards in Gmail
The “summary cards” feature of Gmail is not new; it is Google’s way of helping to make your emails easier to manage, consolidating information about, for instance, purchases you’ve made. Now things are being updated with live updates and “action buttons”.
Across four categories -- purchases, events, bills and travel -- summary cards provide at-a-glance information at the top of your emails. The new actions buttons make it possible to quickly add entries to Google Calendar or Google Tasks so you don’t forget important events, but there is much more to the update, including a Happening Soon section.
