Not sure that actually makes sense, since you can have an infinite number of statuses for a post. So how could you possibly add multiple “circles” onto the admin menu for all the various types of statuses?
The “summary” part is also not the intention of this plugin, it was specifically designed for the Listing screen only.
I know there is a Plugin that adds these “summary” items to the “At A Glance” Dashboard area (on the login landing page).
Glance That
Note: The above plugin supports custom post states and supports icons defined by the Post State Tags plugin.
Thanks for the feedback, and link.
Clarification: Glance That supports custom post types and can display standard post statuses. However, it doesn’t support custom post statuses as those are not very well supported by core, yet. It does have good integration with the Post State Tags plugin.
