Sometimes a topic attracts so many replies, and you only want to focus on replies from a certain user. Could the community add a feature that allows viewers to filter replies by user names (through the upper right "options" button, for example)?
You can currently do this. Simply use the "by author" filter on the left hand side of the search results page when searching for posts in a community. To make it easier to only search within a thread, search for the thread name, or something else that's unique within that thread.
