Hi Daisha,
Thanks for checking out our plugins!
In Events Calendar Pro, users do have the option to export events, but there is not an option to mark events as favorites. You might be able to get this working with a third-party plugin though…I did a quick search and found this one, but there might be others out there too. This would work the same way in our free version as it would with Pro, so I would definitely recommend trying this out in your testing environment to see if you can get it working the way you need!
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.
Thanks,
Jennifer
