A great tool with great potential
Response from developer
Hello and thanks for the feedback. Yes we will continue to make the app even better with feedback. There are a number of changes coming and I'll see what we can do about a back button. Can you please contact me via the form on our website and give me specifics about where you want to see it? I assume only the reading pane as searches and collection notes aren't something you would typically navigate with a back button since each instance creates an option in the dropdown to go right to it. On the plans, we ask people to subscribe to set up an account and hopefully continue as a paying member to support development. Cancelling it keeps your account on the free plan.
Dishonest!

Apologies that the description wasn't more clear. I have corrected that. It's my first app and we're in beta so it wasn't as polished as it could have been. I recommend you try the app before recommending people avoid it. You might get excited or at least raise your 1 star review a bit. :) We ask people to subscribe with a membership plan to help support development. They can cancel any time to be on the free plan, even during the free trial period.
