Addresses is a GNUstep address book that consists of a full-featured address book manager application, a source-code compatible replacement for Apple's AddressBook.framework (for accessing and manipulating address data programmatically), a framework of view/editor classes that make it easy to use Addresses from your own programs, and a number of tools. It is easy to use by both users and programmers and can store almost all imaginable data, including multiple phone numbers, emails, and addresses, photos, AIM/Jabber/ICQ/Yahoo IM details, and notes. It supports drag-and-drop and integrates well with GNUMail.
Charmap is a powerful character map for the GNUstep environment, In addition to assisting with the process of picking characters, it displays substantial Unicode data about each character, such as the Unicode name, alias, canonical decomposition, Unicode category, and various representations. It is a useful tool for developers and linguaphiles alike.
