@richard-cox @scures would you mind move this in the UI project? I don't have the permission to do so.
Or maybe link the existing issue, if any! Thanks

[scures]

I don't have permission either @enrichman, pretty sure Richard is able to do it once he's back.

@scures you may need to be in https://github.com/orgs/epinio/teams/epinio/members to transfer issues from epinio/epinio

@enrichman I've added you to https://github.com/orgs/epinio/teams/ui/members, that should help you transfer issues to epinio/ui
