When an event comes from Google Calendar ICS it does not have a URL. I want to add a URL in the description field that will be parsed on import. E.G. In the description I would write myurl[www.testing.com] and it would be used if there was no URL.
I have implemented this (poorly) by editing amr_make_excerpt_from_description($e) to pull out the URL and displaying the excerpt (which is now my custom URL). As you can see this is not a great solution!
Thanks. Your plugin has saved me - I no longer have to rely on Google Calendar SLOWLY refreshing external ICS feeds. Yay!
