At the end of last week, Google released a couple of minor enhancements to its calendar program.  The first is the ability to set an additional pop-up notification reminder - essentially a snooze alert - thereby giving you the option of having another five minutes.  The second enhancement is the ability to hide the calendar from the list directly from the calendar list (click on the arrow) - prior to this update the only way of removing a calendar from the list was to go into the calendar options - note this does remove the calendar information from displaying - the only way to turn it back on is to go into the options.
