I've tried several times to chat here using the iPad (original version - iOS 4.3.5 as well as iOS 5 on the iPad and the iPhone) and can't figure out how to reply to one chat so my reply is linked and the author is notified.
Am I missing something? I'll tag this feature-request as it't not clear to me if this is a bug or something that just hasn't been added yet. I tried to work around it by seeing if the
@nath would autocomplete to the recent chat names and all manner of poking the lines didn't reveal any way to "reply" to a prior comment.
