Code style configuration does not work and is half-baked

As of v4.9.1, Qt Creator has a few apparently conflicting settings that supposedly control a project's code style, which includes:

• Project settings -> editor
• Project settings -> code style
• Tools -> Options -> Beautifier

Apparently each of these options advertises functionalities that overlap among themselves, such as specifying tab/space policies and how to indent code. Unfortunately this means that specifying a coding style will will not have any effect as implicitly a functionality overrides/ignores/renders ineffective other settings. As an example, any change to a project's "tabs and indentation" policy is ineffective as "Code style" appears to dictate how tabs/spaces are used, in spite of not making any of this clear to the user.

It would be nice if Qt Creator used a single centralized editor/code style configuration source that could be applied per object and, more importantly, enabled developers rationalize how and where settings affect these features.
