I developed a Livebook app that contains a list of Kino widgets. You can view a proof of concept running here. Additionally, you can view the notebook source code here.

We can include a link to this app in the README or documentation.

One reason for creating this app is to allow users to see the list of Kino widgets visually without having to run Livebook themselves.

Another reason is simply because it's cool to have this running live. 😎

This strikes me as a sort of Kitchen Sink type thing, which is a sort of reference I've always found very useful for developing UX applications within frameworks.

If we expanded this beyond just Kino.Input to a fuller Livebook kitchen sink, what else would it make sense to include?
