[imp] Auto-display of most recent on login?

[Danny O'Brien]

The way we have it set up now, IMP defaults to the last un-opened 
e-mail on login, which is often a message from months ago that the user 
never bothered to read.

Is there a way to set IMP to auto-display the most recent e-mails on 
login, and whenever the user returns to Inbox (for example, after 
sending a message)?

Thanks for any suggestions,
