Ecamm has announced the release of DockStar, an add-on for Mail.app that adds up to five new-mail indicators to the dock icon. This lets Mail users keep track of email as it arrives in various accounts and local mailboxes. In addition, DockStar brings customizable shapes and colors to the Mail dock icon. Seamless integration allows users to control every aspect of the dock icon directly from Mail’s settings panel. DockStar is priced at US$8. A 7-day free demo is also available.
