It's kind of nice to have something just for the local instance users to use. I think it's a good feature, just not implemented well in this particular front end.
My bad, yes I have been talking about the shoutbox. I don't think it needs media attachments, but maybe some people would like that. Hard to tell because we are on the soapbox 2 front end, pl-fe and it's tucked away in the chat bar. Hardly anyone uses it because it's there instead of on the front page like it is on pleroma.
