@KOTungseth where should we actually put this?

[reakaleek]

I didn't follow the description..

But added a "View as markdown" link in #1686

We should think about designing a button group.. like

| View as markdown | Copy page content | Ask AI about this page |

@cotti can you add this to our footer where our trademark text is? @KOTungseth can have more details if needed.
