Future Platform Feature

When opening up discord, possibly running a game or just wanting someone to talk to, you never know if a friend or friends are already on call with someone else. As easy as it is to ask them, it would be a lot simpler if there was some form of indication letting us know whether or not someone is available to call. Therefore, as a possible future platform feature, as an idea an icon could be added as to represent if people are in a call and would also assist in helping identify a persons availability, as to not disturb them as well if the call is important.
