 Following the changes in #26495, the "At a Glance" Dashboard widget is now
 much less flexible for extending.

 Primarily, the issue is the new `dashboard_glance_items` filter which is
 significantly less flexible than the previous collection of actions.

 Two main issues:

 1. The filter forces all items to be in a single list along with the core
 "glance items."
 1. The filter does not add any classes to added list items, making them
 impossible to style.

 This last issue is particularly bad, since a class is required to change
 the icon associated with a list item in the "At a Glance" list.

 Here's a use case for why a more flexible filter or an action following
 the list but before Version and Privacy info is important from my plugin
 Post Status Menu Items:

 [[Image(http://mrwweb.com/files/wp-trac/at-a-glance-statuses.png)]]

 Note the separate list and list-item icons. To get that at the present
 time, I had to hack out of the existing list with an empty list item in
 the first list and a new empty list with one empty item at the end:

 {{{
 ...</li>
 <li class="comment-count"><a href="edit-comments.php">28 Comments</a></li>
 <li></li>
 </ul>

 <h4>Post Statuses</h4>
 <ul class="ps-post-statuses">
 <li class="publish-status-post-count">...
 }}}


 {{{
 ...<a href="http://localhost/wp3.6/wp-admin/edit.php?post_status=trash">1
 Trash</a></li>
 </ul>
 <ul><li></li></ul>
 }}}

 At a bare minimum, the filter should allow for classes, and the ability to
 create multiple lists would be even better.

 There is a `rightnow_end` action, but it comes after the version and
 privacy information which feels like a "footer" to me.

 The easiest solution for allowing separate lists and wouldn't require
 reverting #26495 would be to simply add an action following the closing
 tag of the At a Glance list. Then the `dashboard_glance_items` could just
 be extended a bit to add unique classes for styling.
