We are using the Pro, hosted version of the calendar to limit the CPU usage on our server, but one downfall is when we integrated the calendar into our WordPress page, when you click on the event, the detail page opens in a pop up.
That would be ok if that's all we used it for, but we send people directly to these events from the social media and on the free WP plugin, the pages would open on it's own page (with a sidebar where we put a call to action )
Now, a person follows the link to the event and they get a popup. Unless they close the popup, they would not even know they are on our website.
I would like to see better integration from the Pro version, to integrate the event pages directly into the theme of the website instead of a popup, just like the WP plugin.
A pop-up increases significantly the performance of the calendar, and lowers the loading time.
