MacMilitia has released a beta version of iChatViewer, bringing it to version 0.4.0. iChatViewer is an iChat utility designed for sorting through iChat logs. The app displays the results within iChat with the Aqua look and feel. According to MacMilitia:
I am pleased to announce iChatViewer 0.4.0, the first public beta release of the software that sorts through your iChat logs and opens them in iChat.
Instead of displaying the logs in the application, iChatViewer opens them in iChat for you, so you can see them in all their Aqua glory.
You can find more information about the beta release of iChatViewer at the MacMilitia Web site. iChatViewer is available as donationware.
