Sorry, also if I wasn't asked I quickly looked into this. Nice work 👍

I just like to recommend to use Material UI v4 or MUI v5, not both. You can do it and Backstage core components still use MUI v4. But I would avoid mixing them. :)

All our other other plugins uses MUI v5. Also not v6. It might work, but it could also result in issues when running later as a dynamic plugin in RHDH because RHDH dynamic plugins handles MUI as a shared library. So I guess you will get MUI v5 at runtime. 🤷‍♂️

But at the end, its up to you. The screenshot looks really nice. 😏

Thanks, @Lucifergene , It looks great!

I have a few questions:

Home Page (design):

1. Can we make the card layout responsive so that if the screen is wide, users will see more cards per row?
2. Can you also display the tooltip "Product you tried"?

3. I noticed that all cards initially have the "Product you tried" badge. Just to confirm, this badge should not appear by default, it should only be displayed when a user clicks the "Try it" button. Is this the current behavior?

Mobile Verification Modal (design):

1. There's an icon in the phone number field, what is it?

2. Can we pre-select the phone number field so users can start typing immediately when the modal opens?
3. Can we format the phone number input to display the phone layout, for example: +34 (000) 000 0000?
4. Can we disable the "Send code" button until a user enters a valid phone number?
5. The country dropdown appears too high, can we make it open below the field and limit the height to display a maximum of seven countries at once?

Verification Code Modal (design):

1. Can we disable the "Start trial" button and only enable it once the user has entered the code?
2. Do we show an error message if the code is invalid?

Access Code Modal (design):

1. Same as above, can we disable the "Start trial" button until the user has entered the access code?
2. Do we show an error message if the code is invalid?
3. I think we need to remove the footer once a valid access code has been entered...

Dark Mode:

1. Can we adjust the badge color to be a darker cyan #009596 only for the dark mode? It seems too bright.
2. Can the banner background (where the "Try Red Hat products" title appears) match the header's color?
3. I noticed that the cards on the Home page and Activity page look different, can we align them to match the Home page style?

Activities Page (design):

1. We should split the content there, so we have the top "Featured" and the bottom (which gray background) all the rest of the cards.
2. Can we make the whole card clickable?
