It may seem minor, but it would be more user friendly if regional spelling variations could be catered for. We get a bit sick of having Americanisms forced on us.

 e.g. When adding a gift in NXT the Payment method of "Check" is offered. This should be "Cheque" for those who spell in British English.

Note: I use Chrome and my Language setting is English (New Zealand) and Spell Check is set to English (United Kingdom)
