Not sure if this will be in the next UI version:
It would be helpful to be able to place the Save / Cancel / Back buttons at the top of the screen as well as the bottom. On longer forms if the data being changed is on the top of the form, users have to scroll down the page if the buttons are not visble.
Thanks,
Tom
PS -- http://www.ConstantContact.com (an email sending service) made this change in their UI recently after feedback from a number of customers.
