Does anyone know how do you delete the individual resources included in the ribbon across the top of the page, i.e. lectionary?
Richard, at the bottom of the tools - program settings dialogue is a section for "Hidden Resources". If you expland this, you can then drag into it from your library all of the resources which you wish to "hide", that is delete. Then, they will no longer appear on the ribbon (nor in your library)
Under file, right click the reading plan you wish to delete and "delete" will come up as an option. Just delete it.
