Poor support and calibre connectivity – Marvin Classic - eBook reader for epub Review

I tried the free app and was pleased with the overall design. My reason for purchasing the full version was to make use of the calibre plugin functionality only to find out that it has not been working for some time. I have contacted customer support and have yet to hear back from them. So many people recommend this app and I want to give it a fair try but it is failing to meet the basic needs for accessing and holding an ePub library.
