The console plugin is super useful for debugging.
It would be cool if there was a console command that printed the XML for the two currently visible pages (or any pages?).
This would be most useful when using auto-generated mz3 files that some other part of your website is making, or when dynamically adding chapters or pages through AS. It'd be helpful to see what XML is actually making it to megazine (or what XML actually made it to megazine, this time).
Admittedly, not the most common use case, but something to keep in mind either way.
