Treat repeated events as a single object
Is your feature request related to a problem? Please describe.
Was using ownCloud a few years before Nextcloud and had no problems with its Calendar app. But after moving to Nextcloud this problem constantly bugging me. Let's imagine that I created an event with repeating every month on the same day of first occurrence, e.g. 11th. Then I decided to move this event with all its repetitions to 12th. In ownCloud I would just drag first occurrence from 11th to 12th and that's it. But if I do that in Nextcloud, one event (first in this example) will detach from repetitions and will move to 12th and became single (no repetitions), and other occurrences will remain in place. If I do that through the right side editor (click "from" and choose 12th then "update this and all future") then due to that bug https://github.com/nextcloud/calendar/issues/2850 first event will disappear and it will be only editable using external clients, and other occurrences will remain in place. So I have to create new event (there is no copy function), fill all descriptions, category, repetitions for 12th, and delete the old one. It's pretty annoying.
Describe the solution you'd like
I suggest that Nextcloud app works like Owncloud, i.e. treat repeated events as a single object. If you move any occurrence of this event to e.g. +5 days forward then whole event (all occurrences) will move +5 days forward. It's intuitive and simple.
Describe alternatives you've considered
As an alternative leave as is, but add "Move to" context menu function to do this.
