Add "View in Front" button to header or hyperlink subject line

For Front email notifications, it'd be great if the 'View in Front' button existed in the header somewhere. When a thread gets too long, you have to click 'View entire email' in Gmail to display that button. Even if something like the subject line of the thread in Front was hyperlinked, that'd make it a lot easier to get to the thread in Front without needing to get around Gmail clipping.
