per-post hide thhreads in P2?

one of the great things about P2 is the way its ajax and front-page comments really facilitates discussion. Unfortunately, sometimes some posts attractc a LOT of comments and others do not. The threads with just a few cmments are well served y having teh thread displayed, but those with many are often best left hidden.

Is there a way to add the ability to hide a thread on a per-post basis? or have a threshold, say 5 comments (but configurable in settings), for which any further comments are represented by “and N more comments – click here to display” text in line? That way long threads would be truncated so they dont dominate teh page, but still are visible with a single click in-line like any other.
