Tools - Preferences

Clicking the anywhere in the Preferences box in the Tools menu will open it up to show three further options:

Hide edit tools
this allows edit tools such as  to become invisible so that pages may be viewed as an ordianry user would see them. The button toggles to become Show edit tools in order to regain use of the edit tools.

Show Deleted Pages
This option is available to display pages which have been previously deleted and is very useful if deletion has been by accident! Clicking Show Deleted Pages will display in the left hand page title column any pages which have been deleted and which still remain in the Firefly.NET database. Any pages which have been purged by the administrator will not show.

Deleted page links show up in grey and, if moused over, have an undelete button  in place of the Modify button:-

Click this and agree to choose to undelete the selected page in the Undelete Page dialog box which comes up and the deleted page will be displayed. It is now a normal page and may be subsequently deleted in the usual way. Click Hide Deleted Pages in the Tools menu to revert to the normal page view.
