This is one of the better readers from a basic UI standpoint, but probably one of the worst from a technical one. You can add files through iTunes, but not whole folders. As for retrieving them from the app, you might as well forget it. You must create the folders in the app separately, either to import into or add to later. These folders also become part of the app and cannot be managed anywhere else. It’s an overly tedious design that hints at poor development or excessive attempts to force subscription without first building the trust that it will be any less tedious.Subscriptions meant to cover the cost of services make sense. After all, some do charge the developers. Lumping in services that the developers don’t pay a dime to maintain should be a separate, one-time fee to cover the cost of publishing the app. I can’t see paying Panels monthly to cover the cost of using my local server, unless they plan to send out techs to maintain it. After my experience importing files, I wouldn’t want to pay for that experience again.There is almost no animation to reading beyond the generic slide. For one of the most expensive apps to own, it is sad to fall short of the stock Books app included by Apple.Overall, I like the basic look of the UI and hope that one day the functionality catches up. Until then, I will continue to sync with Chunky and import the files here to organize when I get to it. If not for the UI, I probably wouldn’t bother at all.
