I was wondering if the "next event" display in the header can be removed, and if so, if there is control over content, such as text or image, that can be placed there.
Please be kindly informed that "Next Event" is a widget and of course it can be removed from the header. You simply should go to: Dashboard->Appearence->Widgets and remove/place widgets from/into "Header Sidebar" using drug'&'drop at the right of the page.
Can this theme be customized so that events have date ranges. Right now it looks like it only supports repeating events, but there is no end date for them. Say i needed an event to start on a thursday and end on a sunday. Is this possible?
You should buy three separate licences in this case. Since we're using TF as a platfom to sell our works, the themes presented there comply with their Terms and Conditions. Feel free to check the below links to get to know how the system works:
