- When you create a page that would get the same url as an existing page it would be a nice feature to inform the user that it would give a conflict, and give the user a chance to either change the page name or the "Use in URL" field instead of just adding -1 to the page. This also gives a problem when you delete the page that dosen't have -1 in the url because the the url for the second page (the one with -1) will change.
- When a page is moved in the structure and the url changes, it would be nice that you automatically made a 301 redirect from the old url to the new and that you had somekind of history over the changes to the url of a page.
And it could also be nice to have a NotificationSubscriber for when a page is moved so you could notify 3. party system that a pages url has changed. - Under known bugs you have a the following bug listet "404 redirect doesn't work when customized urls is set to Page name and ID parameter". Can you say anything about when this bug will be fixed other the the future relese that it says under know bugs?
- Add a OnBeforeSave NotificationSubscriber for at page like you have for paragraphs.
