Replies to comments on photos.

[kjs1961]

How about a way to reply to a comment someone leaves on a photo?
Comments are shown in descending order from newest to highest.
If someone leaves a comment or has a question about a photo, my (or anyone's) reply appears above their comment which makes it hard to follow the conversation.
It would also be easier if we could "@" someone.
For instance, if you commented on one of our photos, we could reply starting with "@DoMyWifeMaster" and you would receive a notification that you were tagged in the reply.
