In my wildest dreams - a program separate from OOTP that can read whatever files it needs to draw from your league folder and then produce a history similar to BBRef. The ability to run this program at anytime of year, so basically you could update your history daily if you wanted to.

Then just view it through whatever browser you use, same as when going to BBRef.
More on a realistic and maybe possible level, everything you said, really wish the game would track MOY Award history, and also in each team history, keep track who was GM and who was Manager, when they were hired/fired/retired.
Also in team history - career leaders for players and Managers.
