Describe your feature

Make the whole OmemoKeys.swift file dynamic by adding several [[MLNotificationQueue currentQueue] postNotificationName:[...] object:self.account userInfo:@{[...]}]; notifications to MLOMEMO.m and using them in the omemo view by .onReceive(NotificationCenter.default.publisher(for: NSNotification.Name("[...]")).receive(on: RunLoop.main)) { notification in [...] }

The view should dynamically show all changes in trust, and newly added or removed keys as well as newly added or removed users in a group (and their keys).

@matthewrfennell That one could be something for you, I guess :)

Notification names can be defined in MLConstants.h
