Add feature request processwire/processwire-requests#186 which adds the configurable option to always use the full clone form. Also updated it to show a count of how many pages would be cloned when cloning children, and added dropdown options to the submit button so that you can optionally edit a page after cloning. Added icons to all inputs as well.
