1. Yes there is an "Upcoming Events" widget option available. You can see this and other widgets in the Appearance > Widgets screen of the
Vantage admin dashboard demo here. The events display as a list in the widget.
2. No, there are no thumbnail options by default. If you are looking to modify the theme, you can also find useful information in the
AppThemes developer center.
3. There are no reoccuring date options at this time, but you can select multiple dates for an event.
4. There are no other display options within the theme for events, so it would require customization on your part if you were looking to change this default list view.
5. Yes you could create a child theme, and we definitely encourage this if you're looking to modify the theme as it will save you losing all of your changes in the process of an update. You can find more about creating child themes in the developer docs link mentioned above. Thanks.
