Add circular cycle for navigating works.

Add jumping to the end if you go **up** from the first work and then jumping to the first work when you go **down**.

Right now you have to hit :arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down: to get to the bottom of the list.
