I really like the "save a loan" capability. This allowed me to explain a whole bunch of re-fi scenarios to my wife quickly at a glance. Being able to re-arrange the list was key.
The email feature is useful also with the PDF version.
Adding some integration with the Contacts would allow picking a person from contacts to send the email instead of hand typing.
Nice work.
