Hide unpublished forms on Admin View

I'd like to offer a simple improvement for backend Admin view.

Actually most of users create many forms but uses only a part of the ones.
But usually nobody wants delete extra forms (storing just in case) because the ones could be useful for examples or technical solutions/examples.
After the months/years we get the big list of forms under Admin Part - Manage Forms.
Even if we set a form to "unpublished" state - anyway the list shows them all.

I offer to add the button "Show/Hide unpublished forms" at Manage Forms - enabled to 'Hide' by default.
It will make view of the published forms more compact and convenient, at the same time saving access to full list of the forms (including Unpublished) when necessary.

Best regards,
Serge
