Yes. My site used to have a google based calendar before we switched to Events Booking, and I only recently discovered some of our users actually used the feature to display alongside their own google calendars. I could do this for them via a data export but if an event date changes inside EB it would not get updated in google automatically, so I think this is worse than no calendar at all. So the ability to live link to a google calendar would be valued by at least some of our users.
+1 from me.
I used to use jevents which has this functionality and I found it very useful as a user to be able to choose which categories of events to include in a sync to display as a calendar within my google calendar - I could see all the events in the website calendar from my phone's calenadr app without having to open a browser or visit the website.
This is a feature we'd like to see as well. We are a non-profit and utilize Google Grants for our organization. I like the features of EB, however, some users prefer google calendar. In addition, there are other applications that can link to Google Calendar. For example, we use Asana for project management. This can be synced to google calendar but not directly with EB. A sync to our calendar from EB would be great!
