There is configuration for the formatting style, but it is intentionally limited. The lack of (extensive) configuration is in line with the first goal of the project:
Anyone who wants a formatter that can properly wrap and unwrap long lines in a style that makes sense, while supporting all modern Delphi features. As far as we know, there are no other Delphi formatters that come close in this regard.
This was covered quite extensively in the last thread, and in this issue.
