If Adobe want to make Livecycle a serious platform for developers, then why not open up the bug reporting database the same as has been done with Flash Builder / SDK, Coldfusion, etc? http://bugs.adobe.com/. Most Livecycle devs can navigate themselves around Jira and responsibly search for or log a bug or feature request.
And at the same time get some people from the Photoshop / Flash Builder IDE UI team to work on Workbench and Designer. The UI's are in desperate need of updates to bring them in line with the current UI's that Adobe provide. Designer looks and feels like it has been left in last decade somewhere compared to Photoshop or Flash Builder.
