Thanks for the idea, but it doesn't seem to work like that for me. Clicking on the unread mail widgets either takes me to the Mail for Exchange account, or to Inbox (which one is inconsistent), but never to the message itself or even the message list. This is true whether I have 0 unread messages, 1 unread message, or multiple unread messages.

Not a huge deal, just an annoyance and a step backward from Modest on the N800.
