Currently, the addon displays Restored Coffer Keys as a currency (which is fine), but does not list how many of those keys were obtained within the weekly limit.

this would certainly be useful

You can check your weekly count by pasting this in to a macro in-game.

/script local j,c=0,{"FFFFFF","00FF00","00FFFF","FFFF00","FF0000"};for i=0,3,1 do if(C_QuestLog.IsQuestFlaggedCompleted(84736+i))then j=j+1 end;end;print("Delve keys obtained this week: ",format("\124cff%s",c[j+1]),j,"/4\124r")
