please consider JITSI-1053 for implementation.
Another related issue JITSI-425 (add invisible and NA statuses for Jabber) has been recently closed and says fixed for version 1.0 but nothing was working on
jitsi-2.1.4564.10765-x86.exe <https://download.jitsi.org/jitsi/nightly/windows/jitsi-2.1.4564.10765-x86.exe> version. (and still not implemented on 2.2)
please consider for both GTalk and XMPP/Jabber even if it could be two different issues.
This problem has been discussed for Pidgin project here:
and here is the follow-up for "Shared status" implementation.
You can read more on Shared status here https://developers.google.com/talk/jep_extensions/shared_status
Does JITSI plan to support Shared statuses?
With kind regards,
