A new version of DDT - D Development tools is out. https://github.com/bruno-medeiros/DDT/releases/tag/Release_0.10.0
The major new feature is DUB support (there are breaking changes, please read the changelog and updated User Guide sections for more info).
A lot of the UI has been cleaned up as well, removing inoperative functionality, changing the references to DLTK concepts (such as "interpreters" or "script"), etc.
PS: Thanks to Sönke for bringing DUB into an existence, this tool is awesome! (this could even be an understatement... a package management and build tool is crucial for D's success!)
