Hello Jeff,
In answer to your question, Yes, there are ways to customize the popups and dialogs in Visual Studio 2022 to better suit your preferences. For the issue you mentioned with the Find/Replace dialog, you can disable the "Preview changes" option in the dialog to prevent the light text from appearing over the old text.
To disable other popups and dialogs, you can go to the "Tools" menu in Visual Studio and select "Options". From there, you can navigate to different categories such as "Text Editor" or "Environment" to customize specific settings related to popups and dialogs.
For example, under the "Text Editor" category, you can disable the "CodeLens" feature which displays additional information about code such as references and changes.
It may take some time to explore and adjust the various settings to your liking, but with some tweaking, you can customize Visual Studio 2022 to work more efficiently for you.
I will try to follow your other issues, let me know if this was helpful enough
