Hi,

Thanks for the PR, I really appreciate it. However, this PR includes many unnecessary stylistic and formatting changes.

For example:

ThemeManager/src/MudBlazor.ThemeManager/Components/MudThemeManagerColorItem.razor.cs

Lines 28 to 29 in da26ee1

	private bool _isOpen;
	private bool _shouldRender;

You moved these properties from the top to after the parameters, but according to our usual convention, they should remain at the top.

There are many other unnecessary changes, such as swapping the positions of ColorPickerView and ThemeManager, as well as significant movement of items in MudThemeManager.razor.cs. Reformatting MudThemeManager.razor also makes it difficult to understand the relevant changes you made.

These kinds of stylistic refactors are only allowed by project members.

When contributing to open-source projects, please avoid making changes outside the scope of your feature. Otherwise, it will be difficult for reviewers to review and most of the time it will be rejected. I'm not trying to be difficult, it's just a standard rule in the open-source community.
