Sales Register : Columns

It's great that the column size/ order may be altered.  It would be great though if, when columns are moved, the totals moved with them.  At the moment they don't seem to? 

Also, we work with USD and NZD denominated invoices.  While there are several columns that reflect the NZD value, which have totals shown at the foot of the screen, there is NO total of the foreign currency amounts?
