offline mode

So apparently Origin is going to be completely replaced by the newer EA app later this year.

One feature I liked about Origin that appears to be lacking in the new app was the offline mode and the ability to share single player games across different devices and play them offline while logged in online elsewhere.

(If I was signed into an online game, it was still possible to play a single player game I had purchased on another PC without completely signing me out of my online session).

As of right now, it seems that it's not possible to even sign in without booting my account off of the other device.

Will there be an offline mode added before Origin completely shuts down? Will I have to purchase 2 copies of the same game on 2 separate accounts in order to play a single player game while I'm signed into a different device with my account?

Will there be some form of game sharing or library sharing added to make up for the lack of it in the new EA app?
