The update to an Amazon owned version of this app has made it a horrible experience to use. No smooth transition between panels. Panel feature is useless now because the it's tiny and no longer stretches to fit the screen. No filter for searching comics by publisher, type (graphic, single issue), illustrator, etc. In addition, having a Prime membership doesn't even give you access to free comics so no added incentive to have Prime. Way to ruin this app Amazon...
