There are style tabs in c++ options that have options, but they don't seem to do anything other than update the preview. Documentation does not seem to say anything useful about what (if any?) use is for those other style tabs:
https://doc.qt.io/qtcreator/creator-code-style-settings.html

Since (aside from indentation in General) those don't actually seem to have any effect, I am guessing these other tabs should actually be disabled.

Or maybe these shouldn't even exist if ClangFormat is enabled?
