repeated first line of a thread is distracting

[setharnold]

Hello, I find the constant repetition of the first line of threads very distracting when there are two or more conversations going on -- or people joining or leaving the channel, etc.

I'd like to be able to configure those away -- the Thread Window will do a fine job of showing me the context of a conversation if I need it. (Perhaps a small one-character marker on a message to show that it is part of a thread would be a nice hint that the thread window will be useful.)

Thanks
