Hi and thanks for asking for ideas! I had the idea that it would be cool if Reporting could be used to display the content that is in page properties macros across the wiki. Users could set up additional "metadata" or "properties" using the PP macro, and perhaps Reporting could recognize those. This could greatly extend the reach of Reporting into the content itself. I know that Scaffolding and Live Template can be used for this purpose, however there is less of a learning curve with the PP macro. Then, Reporting could be used to create more configurable reports. The page properties report is not very configurable as far as display goes. I don't know if this is possible or how it would work behind the scenes, but it was fun to think about.
