My suggestions for Google Talk.
Here are my feature request for Google Talk:
* Saving the talk session of any length in a secure exchangeable open format
* Search history
* Intelligent URL/e-mail collector: Collects the url or the e-mail id and remember it in a separate searchable/exportable format.
* Show page rank for any url typed in the talk session and have special right/alt click overloading for it for various things.
* Right/alt click overloading for any selected text in the chat window to search it in Google.
* A plug-in mechanism to the official client.
The official client for Linux.
That's it for now..
Regards & Best wishes,
