A great little freeware app called PearLabelizer does an excellent job where the Address Book isn't quite good enough: Printing all kinds of labels for mailouts.

Eine nette kleine Ergänzung zum Apple Adressbuch, um anständig Etiketten drucken zu können: PearLabelizer.

Hint 1: Add predefined labels like Avery, Zweckform and Herma from the PearLabelizer website. Download and drag & drop the .plld files onto your PearLabelizer preferences window.

Hint 2: Format your font appearance from the keywords in the Address Book tab in the preferences by selecting Keyword e.g. [firstname] and choosing Format from the menu.

Mail Status Control is a nice little app for OS X, that indicates new mail with an icon in the menu bar. it also lets you set a keyboard shortcut to create a new mail message without having to switch to the mail app first. Cool!
