Add Unread email filter to message screen. The current chronological list for email is not very useful. I have to troll back many screens to see unread email I know is back there somewhere. Without unread filter I find the email list unusable and am forced away from Nimble back to my email client more than I'd like. I assume Nimble isn't suppossed to replace email - but having the email list the way it is now just falls too sort of useful. I end up doing my work in gmail, remembering a contact then coming to nimble, searching for an email then flaggin it for whatever purpose. So inefficient that I avoid doing it.
