Michael has published a new extension showing how to add buttons to DayBack’s popover next to the Save & Close buttons. The example will add up to three buttons, and includes a few common Salesforce icons for related contact, account, etc. You can also use your own icons or any of the FontAwesome icons DayBack supports.
