andrewjs18 by the way, what's the difference between a private discussion and a DM? aren't they essentially serving the same purpose?
Nah, they are not the same, some seem to be confused about that. If we wanted the same thing we could have just asked FoF to pass byobu over to us, and I'm sure they would have accepted.
This extension was created because there was a lot of requests for something solely DM oriented, not linked to discussions.
Byobu allows you to create a private discussion with any number of recipients including groups. You can have multiple private discussions between person A and person B for example. You also have access to all discussion features.
The DM extension keeps a single stream of messages between person A and B (like other common messaging apps). And is completely separate from discussions.
They both serve different use cases. Though I understand that many had to use byobu for a lack of alternatives when their use case might have been more like what the new extension offers.
