I'd like to see a complete personal financial picture. Not just some bank accounts and credit cards, but all of my most important accounts. Mortgage, car loan, student loans, 401k, Roth IRA and pension would be my list. I think this hits most of the major ones most people deal with.
mint just feels incomplete, like "just part of the story" without this.
Oh you know, it could call me a drunk or warn me I'll end up just like my good-for-nothing father. It's going to take something on this order to get me to change my hedonistic ways.
It would be great if Mint could show me information about the rewards associated with my credit cards. For example, show me how many reward points or how much cash-back I've earned on my credit cards. Show me the details of the rewards program (e.g., 3% cash back at Amazon.com, 1% cash back on all other purchases).
With all of this information, then the real magic could begin. Mint could analyze my reward programs and tell me how to maximize my rewards. For example, if I get 3% cash back on groceries on one of my cards, but Mint sees that I buy some groceries on my debit card, it could tell me things like "Based on your spending trends, you could earn $2.57 in cash back by buying groceries with Card XYZ."
