Replace light/dark toggle with icons

[Dannyholt]

Can you guys consider replacing the current light/dark mode toggle with separate icons similar to what Ionic have done on their docs.

I can't speak for anyone else, but for me, the toggle just doesn't go with the rest of the style of the nav and takes too much space when compared with a single icon.

I have the same idea. Sent #6717 to discuss this change along with a few others.

also agree with this 👍 , and having a smaller theme icon would also save some useful navbar space
