Suggestion:
I'd like to suggest that Logos add a way to mark books that you have read as "read" or "not read" or "in progress" - in the Library view of Logos 4.
I don't know if this has been suggested before but it seems to me, with the large amount of books I have available in my Library (Scholar's Gold), that it would be good to be able to tell (at a glance) in the Library view if you have read a book or not.
