I've been using this extension for years, always been happy with is.

One feature request: I would like to have the ability to have an email account added, but for it not to include emails from that account added in the little red number. (I have my wife's email accounts added on the desktop, but I don't need a running tally of how many emails she has unread, and I don't want to be bothering her and telling her to clean out her email accounts.)
