For Spectators

[Ogre]

Let us click the player name to access their dump.

Maybe the player doesn't want the spectator to overwrite his last dump? If you aren't aware, there's only file for the ongoing character dump for each player (account) per server, even across game versions.

You can just ask the player in question to dump the character for you, I don't remember anyone who refused to do that when I asked. Keep in mind console players don't see the chat at all.

No, there's messages for console players. The notification is easy to miss, so you may have to wait a while for them to see the message. There's no good mechanism for them to reply though. Replying using the command to enter a note into the game log seems like the standard.
