Simple and effective – Left to spend Review

I agree with all of the positive reviews, but I would like to second the request for a bit of a history function. Even to just be able to see the last 5-10 expenses so I don't forget or double enter something! Example: I buy a sandwich for lunch. Later, stopping at a store on the way home for work, I ponder whether I added it or not, but I can't tell whether I'd be including this missing data, or charging myself twice as much against the balance! Just a quick list of the last few entries would prevent this, and be pretty unobtrusive.
