Entering channel name with @ should change button title

[nesium]

The "Create Channel" button title should match the application logic…

// Join or create room?
if (jidString.includes("@") === true) {
  // Join room identified by parsed JID
  roomJID = await Broker.$room.join(new JID(jidString));
  // …
}
// …

and change to "Join Channel" when the channel's name contains an @

Actually I think that "Create" and "Join" should be clearly separated.

Say I have a private room "abc" on the same server where my account is and want to join it.

I click "Add a channel". Should I enter the full address here even though it's the same server? That would differ from the behavior of joining a public room.

So I enter "abc" and click "Create Channel". The web app now tries to find the room "abc" by calling findPublicChannelByName which fails, since the room is private. It then proceeds to call createPublicChannel which creates a new channel with that name but a different identifier.
