Neurotic app. Crashing of nowhere in the middle of creating. Not auto saving the progress as it 'declares' thus after it's random bouts of restarting I have to start from start. Wasted my hours of time as it didn't saved my progress and restarted the whole app on it's own. And it modified stuff on it's own. Like undid the changes I made to the graphics to default. Else the features and tools are really nice. Worthy of 5 stars.
