A publishing program can provide continuous and real-time feedback on possible design problems while a document is being edited or created. The feedback can include displaying a user interface that has a real-time list of any design problems that may be a result of the current edits or creations in a document. The list is updated as the document is being created or edited. A user can toggle between the list and the document as often as desired. The list can identify all current potential publication problems of an electronic document as well as the types of the publication problems that may be present in an electronic document.
