By default, transactions shown on the main screen are sorted by date.
Clicking on any header (except Balance) will cause all
the transactions to be sorted by that field. The balance column will disappear when clicking any header except Date. Clicking
the date header will bring the Balance column back.
Sorting allows you to find transactions by date, check number, payee,
amount etc. You can also sort by 'cleared' to group entries that have yet to clear the bank. This makes it easy to locate and 'clear'
transactions when they 'clear' the bank.
