In the browse and search pane you can customize your column view. Fred allows selecting a predefined set of columns or to create and save a custom selected set of columns.
The predefined column sets are all the document types defined in the Alfresco document model. Selecting one of these document types will show all metadata fields related to this document type in columns.
You can pick the columns you want to add in your custom view. This view will be set as the actual view and maintained when closing and reopening the repository.
