Hi Alex,
Thanks for reaching out!
To increase the number of events listed, try using the shortcode version of the widget instead: [tribe_events_list limit=”20″] You can set the limit to whatever you’d like.
To remove the end date, you can use a snippet similar to the one in this post (see our themer’s guide for more info on customizing our plugins). Or, you can remove the start and end times by adding some CSS to the Additional CSS area under Appearance > Customize (if you have one) or to the style.css file in your child theme:
.tribe-events-list-widget-events .tribe-event-duration {display: none !important;}
Let me know how that works for you!
Thanks,
Jennifer
