Implement File Sharing Notifications
The following discussion from !645 (merged) should be addressed:
It would be great to have chat state notifications for recording an audio / video message or choosing a file as well. The word
typingwould be insufficient then. My suggestion is to use
return tr("%1 is composing").arg(displayName);
It should be accepted as an Experimental XEP first but it is in my opinion not obligatory. It must be implemented in QXmpp as well.
