Dirk,
I do the same thing that you do to import ics files, and I agree it would be nice in principle to be able to right-click on an ics file and have a popup menu option to "Add to Calendar".
Some users however have multiple shared calendars, so the new UI you are proposing might need to enable users to choose into which calendar to import the ics file, yes?
And if there are resources on the domain, like conference rooms, projectors, etc., would you want to have an easy way to invite them to the event as well at the same time?
I do think this is a good idea, I just think the use cases need some fleshing out.
And there is an already-existing RFE in bugzilla covering this:
https://bugzilla.zimbra.com/show_bug.cgi?id=40554
Would you consider adding your specific use cases to the RFE (and voting for it)? That will help to get it on Zimbra's development radar.
All the best,
Mark
