Several places in NXT require the user to use the mouse to click into the field to be entered instead of it being ready to receive data as soon as the page loads. Adding a new address is one example. When you click 'Add address' and the form for new address entry opens, the first field (Type) should be focused and ready to receive data from the keyboard without requiring the user to use the mouse to click in and activate it. This slows down entry considerably.
