If it's only colouring the visible index listing, that's fine with me.

I don't use scoring.

I've got this:

     folder-hook . 'push "<tag-pattern>~P~N<enter><tag-prefix-cond><clear-flag>N<untag-pattern>~T<enter><end-cond>"'

which takes any new messages from me and cleares the new flag, as I 
think I should already know their content :-)

This push was important because I used to uncollapse any thread 
containing new messages. I'm not doing that now though, but I colour new 
messages and threads-with-new anyway, so it still has value.

BTW, is there a way to tell if the current message is a collapsed thread 
in the index or just a single message? There are times when that would 
be useful.
