Right now, then user (during editing web-content) trying to set "Display Page" for edited content tree with all site pages is displayed. Pages without "default publisher" grayed and not allowed to be used.
In case we have site with many pages (actually more then 20 pages) - it become very hard and tooks for content editors alot of time to find specific page and select it.
Do we really need to display all pages? may be it make sense to display only pages with default publisher and their parents (to keep structure of site in this tree) - it will make content configuration a little bit faster.
