I have some question about to create and delete page types. I tried this scenario:
1.) I created a new page type (with name tmp) with "Allowed parent page types" as "Root (CMS.Root)"
2.) Then I created page in me site inherited from tmp type in root of me site
3.) Then I changed inheritance type for page tmp to none
I looked back to me web and there are no changes or mark, that this page is no more allowed to inherit from root. There are also no message (when I deleted page type) about pages which is currently inherited from. Is it possible to add some extra message (when page type parents is changed or delete) or mark to tree about this ?
