I don't think Jetpack has those features. It's nice for what it does, but don't think it does what you mentioned. But.... Question and thought for you: Are you running the SFC plugin on WP 3.5.x? I just looked at the SFC plugin page on the wordpress repository, and the author himself says its only compatible up to WP 3.3.2 and suggests trying the official Facebook Plugin first. In the support forum there he goes onto say that you should use SFC only if it has features the official plugin lacks, and that SFC is "much older" than the official plugin. I appreciate his honesty, but his plugin has some cool features that the official one doesn't (yet). So I'm curious if you or others are running SFC on a WP 3.5.x install and, if so, how well it works.
