A page that lists the stuff that you did that day.
ie:
Killed Claw of Jormag (3x)
Ran Crucible of Eternity: Submarine (1x), Teleporter (1x), Front Door (2x)
Finished a FotM on level 1-10(1x), 21-30(2x), 31-40(1)
Basically an account wide reckoning of what you did and how many times you did it. So that you don’t have to mentally keep track of the diminishing returns on everything.
The data is there, it just needs to be displayed.
