What issues does this PR fix or reference?

Part of #8571

There is a glitch on the Download button after the download is finished and the extension is removed from the list (the button of the next extension is displayed as Downloading for a second). Visible in the video around 0:16. The fix will be done as part of another PR

How to test this PR?

• Tests are covering the bug fix or the new feature

LGTM, tested on Fedora

I like the iterations but IMHO it should be applied in some of reverse order.

1. redirect people to the existing resources being installed (if no cluster then I should have a redirect to kind extension first)
   no need to install something else.

2. enhance the embedded catalog to filter resources (keywords)

3. enhance catalog of extensions with keywords for extensions that can bring a kubernetes cluster (locally or remotely)

4. then include the catalog to this page (this PR) where people will see the page

IMHO the filtering is a pre-requisites before showing the link to the available extensions

---

On the page showed by the PR, I would expect maybe a note just on the top of the catalog explaining why it's displayed.

kind of sentence : Don't have a kubernetes cluster, install one these extensions to help you to bring one:

No, there is still work to do on this PR

Not sure if it is to be reviewed as it is a draft

The features are now ready for review (still in Draft mode as I need to write some more unit tests)

First I want to say: Love it!

A small issue I encountered

I do not see minikube option, even tho I have it installed and enabled

I tried enabling/disabling it, same result.

Thanks :)

The logic should be the same as the "Create new..." button in the Resources page, for Minikube. Is the button visible there?

I have seen the same behaviour with another provider, where the button was not visible because a resource was already declared. Perhaps you already have a minikube cluster running?

as a feedback, I think my eyes are more seeing the installation of other extensions than seeing the ability to already being able to create a cluster.

I don't know if we could balance more the upper part or add some divider between the top and bottom screen, or making more appealing the links to create a cluster

but it could be follow-up as it's a personal view.

Oh yeah, the minikube executable is not installed, therefore cannot create a cluster. That's a bit problematic, as when the user click for the first time to install the extension it would not allow him to directly create the cluster, since it would need to download the CLI first

[jeffmaury]

LGTM.

In line with @benoitf comments, having more focus on Create would be nice

@ekidneyrh would you have some advice to make the first part more visible?
