Scrolling through your friend list and messaging them if they wanna do a raid, nightfall, etc, can be a lot of work till you find someone that hasn't done it yet. So my feedback suggestion is a ingame checklist that shows which activities your friends have done when you hover over their name. This way i can see which one of my friends still has to do the raid, nightfall, trials, etc. This will make it a lot faster then sending messages or lfg. Maybe for Destiny 2?
