I agree with 100% of this but the only other thing I would add is the option to have trailers be played when clicking a game in my library. Since I have so many games from sales and what not that I need to be sold to play a game I already own or have a filter showing all purchased games in a grid that I can browse through. having to click on the game go to info and then going to view store page is a chore.

I actually watched this video a few days ago and it's an amazing new look. Wish they would get hired by Value to design the whole system as it's impressive.
