Events Calendar Customization
Thanks for reaching out!
Currently, the month view (part of the free version) comes with a tooltip, which you can customize by following the instructions in our themer’s guide. This tooltip does include the featured image.
Pro does come with some additional views (week, photo, and map), but it does not include additional tooltip functionality. You can see a demo of what these look like over on our demo site, wpshindig.com.
We do offer full refunds within 30 days of purchase, so if you’d like to take Events Calendar Pro for a test run, feel free to do so! Please let me know if you have any additional questions.
Unfortunately we cannot provide technical support here in the Pre-Sales forum, but to get you started, the files for the bar can be found at wp-content/plugins/the-events-calendar/src/views/modules/bar.php.
I hope that helps!
