Calendar widget, custom fields

http://wpdemo.web-dorado.com/event-calendar-wd-widgets/

1 – Can this widget instead of clicking the day and having event list show on bottom, can I , with CSS, have the list of events show as a tooltip when hovering the day?

2 – Do I have the ability to decide what details to show for each event in the list of events when I click a day? For example, I only want to show the clickable event title, not all the time and location, etc….

3 – Can I add additional data fields to events and show them on the event detail page?
