I agree - great idea. As a recent purchaser of XFrog, I read with concern that version 4 will be released as a plug-in, as this seemed unlikely to be available for use inside Vue. I have not been able to discover whether there will also be a free-standing release of version 4. AThis announcement of a possible "export to Cue" format is encouraging. Any clarification of the relationship between the two applications in the future would be welcome. (I have tried posting this on the XFrog forum, but received no replies.)
