You can filter Expenses in the Simple view by name or client when clicking on the filter icon.
In order to get most out of the filter option, you should use the Table view and columns dropdown to select which columns you wish to display.
That will allow you to filter expenses by name, project, creator, amount, date, status, tags or notes.
If other filters are pretty clear how they work, if you use the Date filter you can select to display expenses between two time intervals, you need to select a start and end date by using the arrows. And if you click on “[…]” you will be able to select more options.
The amount filter also allows you to select a fixed amount by using “=” or you can select greater than, less than or not equal to.
