Trillian Log Viewer displays your chat history.It allows to browse through the chat logs in a tree view. You can also search a chat log and highlight specific words. The application is quite slow when the logfiles are too large. You may also set Trillian Log Viewer as the default log viewer in the Trillian preferences (Note: Trillian 3.1 does no longer include this option, but you may specify a default viewer in the talk.ini file of your user profile: Viewer=PathToYourViewer).
