Options - Calendar Tab
Options relating to your calendar alerts.
When a calendar alert is issued, there is an audible alarm (a zing sound) to catch your attention. You wouldn't be the first to find this sound annoying, so you can disable it here.
Have you ever received a slider alert popup window, only to have it disappear again before you've finished reading it? Your calendar alert may have quite a bit of info in it, so here is an option to add a Close button to the calendar slider alert (only for the one issued at startup). It remains open until you close it.
