Inconsistent styling within Qt Creator interface

It seems that styles used for controls within Qt Creator interface are not consistently the same. An easy way to identify controls (regardless of platform) which haven't been customized yet and fall back to Basics/Default style, it might be good to do a build of QtC with :/qtquickcontrols2.conf where all the [Basic/Pallette] entries are all "red". Which will enable one to find controls which don't have a consistent appearance. Then it would be easier to have a proper and thorough visual review for all desktop platforms at once and then unify the styling of those controls in Qt Creator interface.

As an example, the dialog interface shown in the attached image has a couple of issues with visual appearances on macOS:
1) the expand/collapse arrow next to "details" is black and too big when compared to (for example) the equivalent icons in MacOS finder
2) the "Add..." and "Remove" buttons have what appears to be "Basic" style rather than MacOS and the font is way smaller when compared to other buttons.
3) "Choose..." and "Create..." buttons are not on a same level (not a styling issue)

So the suggestion would be to give a more consistent visual appearance for the controls which would result to better user experience and give a more native appearance for the app.
