thx for the fast response. “you’d have the possibility to change events on the phone as well then.” Wouldn’t I have this possibility with the feature requested above?
Moreover, many people have dropbox/teamdrive/etc. already installed on their devices. When they choose to look for a sync solution for their address books/calendars, they do not necessarily want to set up an extra calDAV server, which would mean yet another cloud storage solution on their devices. I think my feature request therefore would be used by quite some people.
As far as I know there currently is only ICSSync which is capable of syncing from local ics files. Would be great to see an OS solution, too! (Just flattred bitfire btw)
