I know I posted one of these before but i just wanted to bring it up again. As for the other suggestion i have well... Just listen.
1. Mobile Notifications... (There was a little confusion before im going to set the record strait)
The main Idea is that for a CERTAIN SPECIAL contact you could tell it to send you a mobile message via SMS. Now I'm not saying that Plus sends it through Itself requireing some agreement. But instead it sends it to you through messenger.
Now some of you say: /page person@hotmail.com Hello.
But that gets an error saying Cannot Page user "Person@hotmail.com Hello"
2. Choice of who can see your mobile device.
Eg.
Looking at the picture you understand that you can allow people to see and send messages to your mobile device. Now I was wondering how you could allow only SPECIAL people to see your mobile device.
