An overview of the ideas concerning the marking of email headers in the Inbox Column. The goal is that the user, by clicking the right hand area of the card (the red circle) will expand the thread and display messages in it - while still being able to, at a glance be able to discern the number of emails in a thread that is already read, the number of new emails in an old thread as well as see how many emails there are in a new thread.
Any reason you choose red as a color for the unread indicator? Is this using the kirigami/breeze palette? How doe they look in a list close to another? Where is the "important" indicator?
