One minor feature that jumped out at me that I really love (mostly cuz I'd been thinking just last night that "wouldn't it be cool if...?") is the ability to disable any or all of the awards. This is great for players like me who start way back in the early 1900s. Hearing about the 1909 Gold Glove winners messed with the immersion factor a bit.
The one disappointment so far is that the drop-down option for quickly and conveniently changing a player's uniform # didn't return, in spite of a lot of people asking for it over the 12 months...
