Creation of a full-fledged demo map

Since the application is getting more and more powerful, that may be handy both for testing and demo purposes to provide a demo map that showcases several key features with some data, what do you think?

Along this line, at the moment, the demo is a separate extension, it's a good idea indeed if we foresee that this section will become quite complex, but on the other hand it makes the installation process a bit more heavy, for the typical user willing to have an example at hand. For this reason, I would rather suggest to bundle the demo map(s) into the the default extension for now (it could consist of single map in the end, with all features), and consider a split later on, only if the demo is getting really heavy, what's your view on this?
