Has someone moved "Mark site read" elsewhere?

When it comes to the breadcrumb, I have managed to put three different streams there, yet I removed "Mark site read" to make room thinking that not many used it. (Plus it's dangerously close to Unread Content where it is anyway)

Now with my site finally live after an upgrade from 3.4.5, a few members have asked for it. They still have it in the mobile version, but it would be good to put it back somewhere in the desktop version. Has anyone moved it to the footer or the user menu (or somewhere else) and cares to share the code please?
