I am hoping for a collaboration of @truonglv and @NixFifty in this case, as it would be the number one killing USP to have BOTH add-ons installed: The feature to actually SYNC Social Group Calendars with the "Calendar" add-on from NxFifty. @truonglv please check out my suggestion here: https://nixfifty.com/threads/calendar-sync-with-nobita-social-groups-calendar.2965/ I just post it here to make you aware. NixFifty has reached out to you. I very much appreciate that. Thanks.
