Someone has created a post on the Idea Exchange asking for support for Delphi. Please take a look at it and give it a vote and or comment letting us know what you'd like to see with the support of Delphi.
If that idea is also not exactly what you are looking for, please create a new post for what you'd like to see.
Note: The Idea Exchange can only be accessed by AppD Customers (this does not include trial or lite users)
