I go invisible when it's late and I don't want to interact with people but often forget to turn it back when I reboot steam the next day
Same with Do Not Disturb
Sometimes I need to turn it on for certain games but then I forget to turn it back off leading me to miss messages from my buddies

I think it would be nice if there was a way to go invisible or Do Not Disturb and then after a set amount of time it sets you back to being visible or turns your notifications back on
