The Sales Register date filter is annoying. Every time you search for an invoice you there are a bunch of extra steps. I wish under the date filter section there were radio buttons with pre-filled...
A similar suggestion would be for the date range to show at least 30 days. It is annoying to have to select a date range at the beginning of the month when most invoices I am interested in are 'recent'. So, for the start date, a 'recent' radio button could select today's date but in the previous month.
