[Dark Mode]: a suggestion

[dynabler]

Not an issue, more of a recommendation: it would make more sense to have a dark mode option like pretty much everybody else instead of a dropdown menu. It's a concept everybody is familiar with, a click/toggle button. In case of keeping the drop-down menu, I suggest using it as some sort of showcase of Lit option, with a link to docs and/or explaining in short sentence what makes it special.
