I have been using Logos for a while now, and I love the rich resources with all the interlink provided by the powerful search engine, however I do felt that the mobile app need to be more furnished.
for example the sync panel on iOS, it just doesn't work how we all want it to be, when I am learning Greek with ESV in the top, and NA27 below, why couldn't I see the word I highlighted in ESV been highlighted in the Greek, similar to the way Accordance behave....
