Make more icons. Missing a few, one I can remember is a tooth, for example or something that relates to dentists. Another one would be massage therapy. Other would be car wash. I know there's a car, but I like to keep track of how much I spend in car washing. Also, all categories should be visible at all times, which they're not. That makes me create "new" categories everytime. Categories should be sorted by most used, least used, a-z, z-a and we should be able to choose that.
