I was replying to comments and suddenly something struck my mind.. "It would have been cool if I knew whether the deviant is online right now!"
Then I realized that even If I wanted to see the deviant is online or not (from the friends menu on top-right of your screen) he/she has be in my watch list.
Hence, I think this small suggestion would be very to apt to see if any deviant is online or not at any moment (despite he is in your watch or not). It will also increase your social communication with any deviant all over DA for sure!
Comment on what you think about this suggestion.
