Ooh, update (because I didn't read/comprehend it throughly the first time): I would like this outline thing in addition to the current implicit indent style-- I find the indenting nice because I am very visual (and don't always read/comprehend/notice all words all the time), so I don't want to replace it with alphanumeric things which I must read all of to know the threading. But when the comments get long &/ there's complex threading, it would be really useful to me to have this outline format available.
