Copying comment from @MarcSkovMadsen in #3573:

1. Add autoreload

2. Include the Panel Jupyter Preview icon in the Tip

(New users will not know which icon you are talking about)

3. Remove "construct construct"

One things I would like to see are

Beautiful is better than ugly.

The Penguins k-means example of the front page and the colors should be beautified

Simple is better than complex + There should be one-- and preferably only one --obvious way to do it.

Please focus on one api (probably pn.bind or pn.depends).

[MarcSkovMadsen]

Regarding ugly. The default HoloViews colors could be improved a lot. Especially the light blue for tooltips is soo badly looking and hard to read.

(and in this example there is also a lot of unused space. Why is it not just stretching to the available window size?)

[philippjfr]

Hmm can you check what's up with the fonts in that example. Should be using Ubuntu font but I guess it's not available on windows.

[MarcSkovMadsen]

Exactly. Ubuntu is not available on windows.

Please focus on one api (probably pn.bind or pn.depends).

Definitely pn.bind, not pn.depends. PRs welcome to update any example using pn.depends to use pn.bind. Volunteers also welcome to propose a new default Bokeh theme. Now's a good time to do that, with Bokeh 3.0 coming up.

[MarcSkovMadsen]

Does HoloViz, anaconda or anyone around Bokeh have access to a designer. It would mean so much for Bokeh and HoloViz if Bokeh could get an attractive, modern Styling.

[jbednar]

Donation of design services would be greatly appreciated!

[maximlt]

Yes I'd love some help from a designer, and I'd be happy to see Orsted as a logo on Panel's site 🙃

[philippjfr]

Merging this as a first cut. Many follow up PRs to come.
