Steps to reproduce:

This is not really a bug report, but a feature request. In our company we use a CalDAV server where users have their own personal calendars. We usually have calendars of certain colleagues subscribed to see what people are working on.


Actual results:

Events where multiple colleagues are attending are displayed separately in every colleague's calendar. So if I display my personal calendar and that of my colleague, an event where we both attend is displayed twice, which can makes the display confusing, especially when there are even more colleagues attending.


Expected results:

I would like to see events with the same UID only once, even if they appear in multiple calendars. Maybe a small icon or a different color could indicate that it's a combined event display.

Same issue here. It would be nice, if Lightening conflates the same calendar object (with the same uid) but from different subscribed calendar collection into one single item. Updates of the calendar object should only be written to the pesonal primary calendar collection.

Steps to reproduce:

1) Have several calendar collections at the CalDav-Server (your own calender and those of your collegues)

2) Subscribe to all calendars

3) Create a calendar object in your own calendar and invite your colleagues

4) At server-side the calendar object is duplicated into the calendars of the other attendees (aka your collegues), BUT share the SAME UID (!)

5) In Firefox the same event is shown n-times in parallel

Expected behaviour:

5) Firefox should recognize that the VEVENT-object have the same UID and only show the event once

Strategies to conflate the objects:

a) Use the properties (e.g. color and so on) of the organizers calendar collection (the organizer of the VEVENT in unique) and  changes sent to the primary (i.e. own, default) calendar

b) Use the properties (e.g. color and so on) of the primary calendar
