Hi Great plugin.
When you go to all invoices/overview and set Screen Layout Number of Columns to 2 the Filter section goes to the bottom of the screen. I have tried to move it to the top with drag and drop but it returns to the bottom. If you have quite a few invoices each time you want to filter you have to scroll to the bottom of the page which ma suite some people. However I would prefer it to be on the top. A setting to allow you to chose where the filter sits top or Bottom would be useful.
Also on the filter screen is a section to be able to filter the results by date but only by month. Another useful feature would be if you could filter invoices by date range, with a start date and end date.
If either of these feature request are available please let me know
