right now, when you select language and unit options on the bottom right of the main page, this choice somehow isn't remembered, so that whenever you log off and back on at a later time, this is reset to the default English USD.

would be best if this could be put in either a cookie, or make it a setting option. And then to have this choice also reflect throughout the website, including on invoices.

PLEASE have mercy on non-Americans, which -maybe to your surprise- is MOST of the inhabitants of earth.
