It would be nice if each bookmarked chat conversation would indicate, in the sidebar (where it lists the participants),
- the number of posts and
- the length of time from start to end.
The former is useful specifically in comparing periodically repeated chats (like our Parashat Hashavu'a Chat), and the latter is of general interest.
EDIT: It was just pointed out to me that while the conversation page's sidebar doesn't contain the information aforementioned, the page that lists bookmarked conversations does contain it. So this feature request (to have the metadata in the conversation page itself) is much weaker than I thought. In fact, I don't particularly want the requested feature any longer, and would downvote the request, myself, if I could. I won't delete the request, though, as perhaps others want the feature.
