As comments are made on a feature, sometimes there are questions that come up that are unrelated to the other comments that have been entered. It would be much easier if I could just reply to the comment and the thread is kept/read in that fashion. This way I am not having to hunt thru a list of comments to try and find the answer to a question, or have to write more just to explain which comment I am replying to.
It is now possible to reply to ideas portal comments in a threaded conversation. We will keep this idea open to continue tracking interest in threads for other types of comments.
