For people who use only a few features of receipts, you could add a settings menu in the "MORE" tab where users can choose which fields should be displayed when adding a new receipt. For example, fields such as TAGS, REPEAT EXPENSE, RETURNS, etc could be toggled, leading to a much simpler layout.

If adding these extra options would make the "MORE" screen too cluttered, they could all be collapsed into a "SETTINGS" sub-menu.
