Hey there,
I’d like to see my 0/500 or 500/1000 Ranked wins progression in that tab. I mean I shouldn’t have a create deck and see my ranked/arena wins progress to earn golden heroes etc.
You can simply add numbers to Hero icons and when you mouse-over them you could actually see your progress.
As a long time all classes 60 player. That tab is generally useless for me.
As I mentioned, I’d like to check my Ranked Wins on that tab somehow. Because hey it says " View Your Current Progress" 
So as the detailed part you can add PvE adventures that I missed or a simple single player reminder like," You own Naxxramas, do you want to beat it on Heroic mode?" or something like that in that tab.
