I'm adding the dark mode back in. It was originally there a few years ago, but a lot of things broke when I upgraded from Bootstrap 4 to 5. It also didn't allow the user to select "always light mode" which is a gap that I intend to fix. It will take a bit of time to fix the nuances of the dark theme, but should have it done at some point. For those who prefer dark mode, this would be enabled by default if their OS is set to Auto or Dark.
