Auto-complete email address when composing a new email
Gmail automatically suggests auto-completion of previously contacted email addresses when I start typing in the "to:" box. This feature is desperately needed. I don't know the exact emails of most people I contact frequently, so this is a deal breaker for me.

I also would love to have the ability for Moo.do to remember they keys I used previously to select a particular email address. For example, if I frequently email a person named 'Jane Doe', I would like to compose an email, type 'j' and have 'Jane Doe' be the first one in the list of emails .
