I was looking forward to utilizing the LOTH but it is extremely difficult to navigate. I'm sure it has potential but as it stands, its usage is very limited. Unlike the book which has ribbons to easily navigate back and forth this program has no means to do that so one must go in search of the propers via the content index (even this is a bear to navigate). iBreviary app could help Verbum properly understand how to make navigation more simple for the prayers of the day. I would only recommend this LOTH for research but not daily prayers.
