Hey, I would like to have this feature too! I often find myself in the same situation, but there is a workaround I'd like to share with you. When you press CTRL + F (Windows) / CMD + F (macOS), you will open up the search feature of the browser. This will allow you to search through files without downloading them. Unfortunately, this only works for files with a preview and real text, e.g. PDF files.
Even though it's not perfect, I hope that helps!
