One of the smaller, but still useful, features of Sente for iPad is the ability to quickly compose an email message containing a summary of a reference along with the PDF (or any other attachment).

The command is accessible from the single reference view in the top tool bar. When you tap on the Compose button an email sheet slides up containing the draft message. Enter an email address, adjust the contents as desired, and press Send. (The attachments appear at the bottom of the message and can be deleted if you do not want to send them.)
And, yes, this feature will be added to desktop Sente in the near future!

Michael, you win! Sente for iPad looks amazing and, if any of us had any doubts, I am sure these have vanished after the previews. Now the question is: when? And, to ask a question that is more under your own control, how much?
When? Whennnnn?
Soon. Soooon!
