Hi. It would be a nice feature to be able to lock a given property for editing, allthough it's showing when editing the page. To lock a property from editing (once set on page creation), the input field (textbox, calendar, dropdownlist, etc.) would be grayed out. Placed in the PropertyData class, perhaps, and editable in the same way as "Value must be entered" when editing properties on a page type in Admin mode. Thanks, Frank :)
