Chax for Mac

From Kent Sutherland:

Chax is a collection of minor modifications and additions that make using Apple's iChat more enjoyable. Features include:

• Unified contact list shows all contacts from all accounts in one window
• Growl notifications for new messages and users changing status
• Automatically resize the contact list to fit the number of visible users
• Powerful, searchable log viewer that can also browse images and URLs from past conversations
• Activity log that displays your contacts' status changes
• Auto-accept file transfers, AV chats, and screen sharing requests
• Always on top option for contact list, message windows and AV chats
• Set font of names, status messages, and group separators
• Option to immediately display new messages, skipping the notification window
• Show status changes directly in the message window
• Additional unread message notifications in the Dock
• Automatically hide chat windows and contact lists when iChat is inactive
• Toggle text status visibility of users
• Properly use ICQ accounts without sending text formatting in messages
