Within the expense module, it is possible to mark certain input values as favourites. This way, your most frequently used fields are pre-filled with the values you prefer. It's especially useful, for example, when logging mileage and using the same addresses repeatedly.
Example:
Simply click the star icon next to the value you want to mark as a favourite, and it will appear at the top of the list by default. If only one favourite is selected (per field), it will be automatically filled in. If you have multiple favourites, the field will no longer be pre-filled, but your favourites will still appear at the top when you click on the field.
