[MarcSkovMadsen]

I plan to contribute some improvements (primarely docs) based on my experience teaching a new user Panel.

Unfortunately the getting started app displays

I'm on the main branch of Panel and get this when I drag the top left slider.

I see UI tests failing. But I don't think its related. I believe this is ready to review (and merge).
