At the moment, the options in "Thread Tools" are Edit, Delete and Move a thread. I'd like "Lock Thread" to be there as well (and probably Unlock as well). At the moment, if I'm reading a thread that is going off the rails, or I feel should be locked, I seem to have to go back to the thread list, select the checkbox by the thread and then lock it. It makes more sense for me to be able to lock a thread while reading it, rather than from the list of threads.
While I realize this is one heck of a thread necro, I totally agree with wwwicked on this one. I had no idea you could hit edit and do that. I have been going back to the thread list and doing it there.
