In this post you tell to edit "components/com_eventbooking/view/event/tmpl/simple.php" to modify simple layout. This ist just hardcoded and after an update the changes gone. Is there an other way or could you implement an option, where you can choose, which fields should show up in simple-view? That would be great!
