Following up on a post to the users list "Recommended CalDAV/Calendering for RC":

I tried and failed to figure out the current status of CalDAV in roundcube.
It seems that success stories of roundcube -> caldav server tend to use a plugin from the now defunct myroundcube site.
Talk of CalDAV from kolab seems to be about the server, so roundcube -> kolab using CalDAV (or "iRony"):
https://kolab.org/news/2015/02/13/roadmap-kolab-3.1-irony-included
Thing is, there is the tantalizing
https://gitlab.awesome-it.de/kolab/roundcube-plugins.git
though oddly, looking in its master branch, there is no plugins/calendar/drivers/caldav directory.
So where should one look / are there any plans for a roundcube calendar plugin to talk to a standard issue caldav server?
Cheers,
