Although I dont have many "new" ideas, I'll still echo some of others wishes as I share them as well.....
-Expanded Class A-I would love to see Class A be a full 25 man roster(unplayable is fine). And then possibly add a 10-15 man Rookie ball roster.
-Real contract stipulations- Opt out dates, (vesting)options, no trade clauses(full and partial), extensions, etc. If its in a contract, put it in the game!
-GM's- I know you the player play the role of GM, but playing the role of owner would be great. Your GM would obviously have certain attributes and tendencies that would effect outcomes. Perhaps he has a reputation for "asking too much for players" and thus other teams are less likely to want to deal with him and thus your organization.
-Merch- I know some dont like it, but I am one that does. Picking and choosing merch and setting prices can give your franchise more money.
-Agents- It doesnt need to be a different agent for every player. It can be a handful of agents representing everyone(or even a handful of made up agencies). Different agents get different reputations etc....then you would know what your getting yourself into when you try and sign a "Boris Scott" guy in the offseason
-Players of the week/month- It'd be a nice little thing to see at the end of the week/month. Some people I'm sure dont keep up with everything going on in their 'chise, so it's good to know whos tearing it up.
-Expansion and relocation- It's high time for it. Perhaps only expansion once every X amount of years. Maybe you get a list of cities and you choose one and then the computer randomly selects another. And the same for relocation, every so often. Perhaps its offered to your team first and then if you decline it goes somewhere else or something.
-All unis available- I would love to have access to every uniform from every club.
-Retired players coming back as coaches- pretty self explanatory.
Secondary pitcher positions-(doesnt have to be franchise exclusive) I'd love to have a guy listed as RP/SSP(spot starter), or RP/CP so if my closer goes down they cpu would know who to slide into that role.
-Something more interactive post game- This one Im not too sure about, so Id love some thoughts....sometimes after a game is over it just seems bland. Perhaps some e-mails, or interviews with the media or something
