1. Create a meta-guide that links together all the individual passage guides applicable to a lectionary entry and permits the meta-meta level for a liturgical day. This is similar to allowing a book level Guide contain the individual passage Guides or a topical series to be pulled together.
2. Allow user created Lectionary/Reading Plans that have short, repeating cycles e.g. 2 week or 4 week cycles. Note this is equivalent to short calendar devotionals which are also needed.
3. Allow a note to be attached to several verses/selections at once - e.g. tying scripture, Talmud and Early Church Fathers into a single neat package
4. Add a link to The Text This Week to the Passage Guide sermons resources section. It includes links to exegetical materials, sermons, art ... and by the way it recognizes lections as pericopes which Logos also ought to do.
5. Devise a Bible multiple passage layout (beside each other) for lectionary entries and parallel/harmony entries. We already has a "compare text" for multiple occurrences of the same passage. Why not for related passages? Of course, the user would be able to create their own parallel/harmony entries to display.
6. Permit the use of Scripture links in the Prayer List - and allow the Prayer date to be either liturgical or secular.
7. Admit that lectionaries and reading plans are essentially the same thing - given readings for given dates - and allow fine control of Reading Plan entries. This also makes provisions for the user to be using multiple lectionaries simultaneously - Sunday, weekday and morning/evening prayer is a common example.
8. Allow the creation of Reading Plans from lectionaries so that one can mark elements as read.
9. Include liturgical date as an indexing element in Sermons.
10. In the Guides, add a section for historical sermons - selected by passage or liturgical date - as well as Talmudic and Patristic sections. Use an appropriate ranking routine to fill them.
