I would like to see the addition of an attachment library, so you can upload images of receipts at the time of purchase instead of having to keep track of the receipt until the transaction clears.
Adding automatic receipt matching would then be the logical next step. This is similar to what several bank credit cards and corporate expenses programs already do.
i added my vote now, nearly three years after my last comment. The basic features which needed a lot of work back then have all or mostly been addressed. Luxury features like this would be a nice add on.
