While I expect they you'll make it all configurable, - just in case:
personally, I don't care for the number of unread messages, as in some cases I have hundreds of them in a particular folder, or even in the INBOX.
So, if the number of unread messages can be configured not to be displayed, I'd appreciate that.
The number of new messages, - that is different, and would be nice to see (but not critical).
Thank you!
