Yes, that's by design. These rooms are meant to be completely ephemeral and private amongst small groups of peers. It's critical to ensure that anyone who is connected is able to quickly dispose of the room for security / privacy reasons. Once a room is created, there is no "admin" or "host" per se, just a short lived private space.

And if you're not a small number of trusted participants (e.g. anon participants, not all of whom you trust, or enough people that one might make a mistake or delete before everyone is ready), that's not going to work. See the example forums being created and deleted above. They could easily allow two passwords on setup though to avoid this - one for admins, one for posters.
On the button placement, it really would be better elsewhere - it is not related to the text submission entry, so it belongs at top somewhere, along with the sound, which again is a forum-level setting.
