Small release on top of 4.1.29.
Canned chat now marks the receiver's admin. If you are signed in with the admin password, your lines read User 3 (admin) rather than just User 3 — suggested by Saber. This is a room where somebody may be asked to stop tuning, and "please hold" from the person who owns the receiver is a different sentence from the same words from another listener.
The handle is kept and the mark added to it, rather than replacing the number with "Admin": on a club receiver with several operators, replacing it would make two admins indistinguishable, and following who said what is the point of having handles at all.
It is recorded per line, as the sender was when they said it — never recomputed from who holds the password now. Admin follows the session rather than the person, so the same operator can be admin in the browser and not in the app, and the lock can change hands mid-conversation. Deriving the mark later would rewrite history.
Your own lines are marked too: "You (admin)" is the difference between a request and an instruction, and it is easy to forget you are still signed in.
Android build 322 attached.
