Sometimes, when processing a payment or refund, we neglect to select the correct account from the "Account" dropdown and create an issue for accounting later in the month. Is it possible to have that field default as blank instead of defaulting as the account that happens to have the lowest number? If the user attempts to save a transaction without choosing an account, Populi would not let them proceed.
If this can't be done, is it possible to re-order the accounts without changing the number?
Finally, another alternative that would help a bit would be to allow separate defaults for payments and refunds.
