Hi Michael,
Thank you very much for your feedback!
Of course, the packager thing was created as a separate "exe" just for a while until we will complete the ultimate Visual Studio Integration we are about to release in 6.2. The integration will be fully implemented and the packager will appear as an additional tab within the project's properties.
You are right regarding the problems, but since there is still no solution from Microsoft regarding the XAP packaging issue, and VWG is one step ahead with Silverlight, by enabling enterprise development upon Silverlight, Visual WebGui needed to provide this capability in order to enable a mechanism to divide a large application into logical packages according to their usage...
However, please note that the packager will not stay in its current format for a long time. I can promise you that :)
Regards,
Itzik Spitzen
