We have re-designed the showing sheet page to be clearer and more functional.  A few things to pay attention to:

1.  Added a public url for you to share your listings selection with the public.

2.  Added/updated options to easily display related information such as public notes and map snippets.

We are looking into redesign the showing sheet feature completely in the near future, and potentially call it Listing Groups.  You feedback would be appreciated.
