The issues that have been identified through support are:
1) doesn't work when you have magic_quotes_gpc enabled on your server... we have files to correct that issue
2) doesn't work when your testing server isn't configured properly... we have been able to address that by correcting site definitions usually to match the remote server.
3) Connection folder permissions can prevent installation on the site. Fixing that is a matter of updating the permissions.
We will be working on ways to address all of these issues, and regret that they slipped passed our QA, but they are all addressable.
You can insert and view content from within dreamweaver, but editing still has to be done from the web page.
