So like Facebook has the online offline feature and I know this application has an incognito feature. I think there should also be an online offline feature that lets you turn off your visibility to others still be able to search and talk to others. The difference between this and incognito would be that incognito lets you be off or not visible to others still see people who are online and interact. With the offline online you would just get people online if you are online or everyone shown as offline if you decide to switch over to offline. This feature should exist just because it would promote people's privacy if they don't want to be viewed or seen by certain individuals and it promotes safety and the ability to search for help if needed without being recognized online or seen as somebody who's online.
