Not yet. We just got out a new bug-fix release for the current version of JFBConnect, v4.2.x. We're working on 4.3 already and are still scoping some new features to add to it. A recent comments view is one we're investigating, but as noted above, it's a lot more complex than it sounds. Basically, we'd need to store all the comments in your local database in some way so that we can quickly pull them on the fly and do sorting and such. It's not something we can just ask Facebook to do for us.
There's a chance the 4.3 release will be out in late August, but it likely won't be until at least September now, just so you now.
Thanks again for your input, and we hope to get this feature in there soon.
