As of August 2019, these are the things I want to do next:

A number of things in Mappage:
Add flexibility to the Places Mapper
Add flexibility to the Census Navigator
Reintroduce scatter plots and add other visualisations

Start article: Counting Christians in the Australian census

These are likely to take until the end of the year. If I still have time & energy for the project going forward, there are many things I plan to do, including revising the article specific to Adelaide.
