Toggle for 'Auto-read' emails

Background

I use my email almost as a task list, and leave emails that still need to be actioned ‘unread’. On Gmail, there’s an option that allows you to leave the post unread until you manually set it.

Request

Create a toggle so that I have to manually select that an email has been read instead of auto setting.

Side note

If I am on an email, there are no options to change the read status
