We still need a "Today" button -- if the lectionary is left in a state away from the current date, there's no quick way of returning back to the current or next date. This works great in L3f, it just needs to be implemented in L4.
Likewise, we still need an "approximation" feature where typing anydate will bring up the nearest date in the lectionary to what is typed. Again, this works great in L3f, it just needs to be implemented in L4.
Without these additions to the lectionary feature, it's not fully usable. It's also a giant step backwards from what the user had available in L3. These shortfalls were noted several iterations ago, but haven't been addressed in subsequent beta releases.
