GnuCash doesn't seem to remember invoice settings when printing. That is,
every time I print an invoice, I need to select the style I have defined
manually, and I also need to select the columns displayed (I don't deal
with tax on invoices because I'm not VAT-registered, so I don't want tax
columns cluttering up my invoices).

So, I would like to see GnuCash have the ability to define a new default
invoice style. Also, I would like to see it remember the columns to display
on an invoice.
