Kudos for allowing different shades of color for credit or debit items. Default as you wish, but please give users the option to customize the recently entered item. For me, that is hard to read and disjointed in appearance. My least favorite trait of Checkbook is that your most recent item is colored very strangely in white text, boldface, with black shadow on a gray background. When tabbing through an entry, the tabbing skips by a drop-down menu - it would be so much smoother to tab to the menu and use arrows, etc.
For example, all data is on one line like a plain spreadsheet, but two lines per entry might be easier to read.
General interface is polished only to a basic level. Checkbook's functionality is above average, and the reconciling routine is a great virtue - well done on that! Checkbook accomplishes the basics but lacks simple things I need, such as ability to drag and drop a mis-entered item from one account to another.
This app is my basic checkbook and credit card tracker, replacing the feature-rich, but aged Budget.
