I have hunted through the interface, and I can't find a setting that would allow hidden files to appear in the list in the file browser. I can find those files by using File / Open, which shows me a standard file dialog, and the options in that allow me to see hidden files (that option is checked on, and stays on). But the list never shows them. How is this preference meant to be governed?

In addition to what others have already mentioned. It’s also possible to configure this via Preferences -> Projects -> Include files matching. This will apply to all projects.
