There’s incognito mode… so clearly there can be more modes. An Away/Brb mode. Manually select or auto set to Away after 10 min inactivity. If you’re messaged while in that mode ir should auto reply with a “Disay Name is currently Away and might BRB.” After 10 min in away mode Idle them out.

Useful when you hand to suddenly answer a door, clean up your cum, send that trick on his way etc…
