Is it possible to make a pageComponent that is both horizontal AND vertical?
Yes, just add layers to pageComponent.content on any location and the page component will try to do the right thing. This is mostly fine if things are aligned, but can get quirky if they are placed randomly.
how about a pageComponent in a PageComponent where one is vertical and one Horizontal? Will both of them work?
Both will work. You could for instance have a vertical page component with *each* of the pages contained in it a horizontal page component. Kind of like a stack of slide shows.
Yeah look at our Medium example: http://framerjs.com/examples/preview/#medium-app.framer
