1) There is no display of child pages at the bottom of the completed page, where you could click and go to the child or parent page. This function was in 5.0.1.
2) When editing the page in 5.0.1, at the bottom of the page there was an "attachments" button, where you could immediately see their number and attachment files themselves. In the latest version there is no such button.
Please tell me where it is configured in version 6.6.1?
