I may be mistaken but I thought if a book was read on iphone or the desktop that the last spot it was at would be updated on the other platform (ala the Kindle). Is this something that is available or am I simply superimposing the Kindle capability on the Logos app? It is a little tiresome (but not a huge deal) to adjust where it is on the desktop if I've been reading a book on my ipod. Thanks.
