• Clicking Submit in the nav bar will always go to the submission portal.
• Show buttons on the portal page instead of small links.

Looks great, I like the cards instead of text links!

Should we center the cards in the middle third of the screen. It's not clear to me why it should be on the left hand side. The submit dialogue is centered:

This is where the cards are on a big screen:

Should we center the cards

Yes probably. Users arrive here from the organism selection page which also isn't centered, so I wasn't sure what convention we're going for. Perhaps we center both pages?

Yes I'm pretty sure we should center everything - that's what we're doing for pages that have undergone a bit more UI development. I think in the beginning we just went for the default/lazy option and didn't care much about how it looks.

If you rebase onto main, the E2E might work again (or at least faster)

I agree with Cornelius' comments, otherwise it looks good!

Nice - some icons might spruce it up even further: https://icon-sets.iconify.design/

Yes! I had a look but decided to get back to this another time (feel free to add them if you feel inspired to do it).
