There are dark themes, so if you want it you can have it. If you want a new theme you can work on it and submit it, or even ask someone to do it for you. But please do so in another thread, as it is a different topic.

I concur.

This is entirely possible, maybe a "Night Mode" button can be added next to the "Help at the bottom of the page.

However, it isn't straight forward for someone that randomly stumbles on the forums and begins browsing it to find that button.
As for registered users they already have the control panel and wouldn't need the toggle.
