Allow Party Members to View Each Others' Current Active Quests

As per title. I have been enjoying this game a lot, and playing with a lot of different friends after getting them into the game. I am replaying Act 1/2 a lot, and whilst I can usually remember what needs to be done, I sometimes forget (or my friends might play a little without me for a bit). So I would like to be able to see what quests people in my party currently have active so I know where to go and give them a hint.

Perhaps make it an option where the user can enable/disable their own quest visibility if for whatever reason they don't want to share, and enable it by default.
