It would be very useful to have access to sent latex code (to correct wrong formulae or add something). I don't know whether it is possible to neatly integrate it (like adding a context menu entry "copy code to clipboard" on the rendered pictures), but at least an option to send the code together with the picture would be great!
We actually just released a new version (1.4) which contains the feature to send the formulas as custom smileys, as long as this feature is supported by the protocol you're using. As far as I know that's XMPP and MSN at the moment, but maybe there are others that I'm not aware of. Whatsoever: when you're protocol can use custom-smileys, than there is no image inserted in the conversation but the markup-code is used as a custom-smiley. So you can just copy you're message and the markup-code will be in the clipboard.
For protocols not using custom-smileys this feature has been added to our list of feature requests and we will look into it. Thank you for your submission.

Thanks, I'd like to have this feature for ICQ so I'm hoping that it will make it into a future release. :)
